Flatlocking: a serger stitch created by tightening the lower looper tension and loosening the needle tension on a 2- or 3-thread overlock. Serge a seam or the fold of a fabric; pull the two layers apart until the serging lies flat and it becomes a flatlock stitch. Upper threads form an overlock stitch while the threads on the underside of the fabric form a ladder stitch.

Floppy disk: a computer medium containing programmed designs that can be stitched on an embroidery machine. Most machines require a separate IBM compatible computer with a floppy disk drive and in most instances, sewing machine software or a reader/writer system such as The Amazing Box™ II. Also referred to as a 3-1/2” floppy.

Jamming: a condition which occurs when thread wraps around the loopers and won't let the machine operate. Usually occurs when a serger is not threaded in the proper sequence. Gently trim the threads that are jammed together and rethread the serger in the right sequence, making sure the loopers are not crossed.

Jelly roll: strips of fabric measuring 2-1/2" x the width of a fabric, generally 44". Perfect for quick strip piecing projects. Jelly roll strips can be cut into sections—2-1/2" square creating charms.

Jet-Air Threading™: an exclusive threading feature on many Baby Lock® sergers. One touch of a lever sends the thread through a tubular looper with a gust of air. The tubular loopers are engaged for threading and released for serging. Jet-Air Threading is used for upper, lower and chain stitch loopers.

Jump stitches: the threads between the various portions of an embroidered design that are trimmed away after embroidery is completed.

Knit fabric: Fabric created by interlocking loops of yarn—one loop of yarn pulled through another loop. Most knits stretch. Examples of knit fabrics include interlock, sweatshirt fleece, and sweater knits.

Layering: Placing two or more layers together for the purpose of quilting. Generally a quilt top, batting, and quilt bottom are layered for a quilt, but if you use flannel or another fabric with loft for one of the layers you may be able to eliminate the batting.

Lengthwise grain: Yarns that run the same direction as the selvages. Lengthwise yarns are usually stronger and heavier than the crosswise yarns. Most projects are cut with the lengthwise yarns going up and down.

Lettuce edge: a rippled edge created by serging a short rolled or balanced stitch while stretching gently in front of and in back of the presser foot. Differential feed is usually set at a minus setting. Use on edges of stretchy knits such as ribbing, interlock, and lycra, or on bias cut wovens.

Pleat: Fold of fabric similar to a dart, but with not point at the end.

Press cloth: Piece of lightweight fabric place between the iron and fabric when pressing. It protects the fabric surface from damage and keeps the bottom of your iron clean when fusing interfacing.

Presser foot: Part of the sewing machine or serger that holds the fabric against the feed dogs as the stitches are formed. The edge of a presser foot can be used as a stitching guide to achieve straight seams.

Pressing ham: Pressing tool with a large curved surface. Use a ham to press curved areas such as darts or curved seams so they keep their shapes.

Pressing seams flat: First step of the two-step procedure for pressing all seams. Press the seam flat, then press it open or to one side.

Pressure control: a screw or knob usually located on the top of a serger to increase or decrease pressure of the presser foot while serging. Turn clockwise to exert more pressure; counterclockwise for less pressure. Use more pressure on heavy fabrics, and less on stretchy fabrics.

Ribbing: Knit fabric used to finish the neckline, waist, and wrists of garments.

Right side: Side of fabric that shows on the outside. With printed fabrics, the design is printed on the right side. With napped fabrics, the nap is pronounced on the right side.

Rod pocket: A tube fastened to the top of a quilt back to fit a rod or hanger that will hold a quilted hanging on the wall.

Rolled edge: the narrowest 2- or 3-thread stitch. Created by loosening the needle thread and tightening the lower looper for a 3-thread rolled edge. When the lower looper thread is tightened, it wraps the upper looper thread around the edge of the fabric. For a 2-thread rolled edge, the needle thread is tightened and the lower looper tension is loosened, wrapping the lower looper around the edge of the fabric. A Two Thread Converter is necessary for a 2-thread rolled edge.

Rotary cutter: Special fabric cutting tool that looks and works like a pizza cutter. Used in combination with a special cutting mat and gridded ruler, it is used to cut one or more layers of fabric accurately.

Rotary cutter and mat: A sharp cutting tool with a rotary blade used in combination with a straight edge quilting ruler and self-healing mat to cut quilt fabric, strips, blocks, and so forth, during the quilting process. Cut through one or more layers of fabric with ease.

Piecing: Sewing smaller pieces of fabric together to form blocks for a patchwork project.

Pinking shears: Shears with special serrated blades that cut a decorative zigzag edge.

Pins: Necessary for any sewing project, pins temporarily hold layers of fabric together.

Pintucks: small decorative folds in a fabric that are sewn or serged in multiples for a decorative effect. Achieved on a serger using a rolled edge or narrow cover stitch.

Piping: a folded fabric strip with cording inside used to add interest and dimension.

Piping foot: aids in preparing a piping strip because the groove in the bottom of the foot helps it glide over the piping as it is stitched in place, close to the cording. Also allows you to make and attach piping in one step.

Pleat: Fold of fabric similar to a dart, but with not point at the end.

Press cloth: Piece of lightweight fabric place between the iron and fabric when pressing. It protects the fabric surface from damage and keeps the bottom of your iron clean when fusing interfacing.

Presser foot: Part of the sewing machine or serger that holds the fabric against the feed dogs as the stitches are formed. The edge of a presser foot can be used as a stitching guide to achieve straight seams.

Pressing ham: Pressing tool with a large curved surface. Use a ham to press curved areas such as darts or curved seams so they keep their shapes.

Pressing seams flat: First step of the two-step procedure for pressing all seams. Press the seam flat, then press it open or to one side.

Pressure control: a screw or knob usually located on the top of a serger to increase or decrease pressure of the presser foot while serging. Turn clockwise to exert more pressure; counterclockwise for less pressure. Use more pressure on heavy fabrics, and less on stretchy fabrics.

Prewashing: Process of washing and drying washable fabric prior to cutting and sewing. Prewashing reduces shrinkage in the final project, and removes resins from the fabric, and helps to prevent skipped stitches during sewing.

Prewound bobbins: cardboard or plastic bobbins that are prewound with thread specially designed for the bobbins of embroidery machines.

Pucker: Undesirable bunching of fabric that usually occurs where two seams of different lengths are joined, such as the seam that joins the sleeve cap and the armhold.

Puckering: fabric that is drawn in and wrinkled around the edges of an embroidered design, rather than being smooth and flat. Often caused by inadequate hooping or stabilization, improper tension, or a blunt, burred, or incorrect needle.

Quarter marks: Points indicated with pins or a washable marker to divide fabric into four equal parts. Quarter marks are used to position and distribute fabric evenly when sewing ribbing or elastic, for example, to the waist, neckline, or the sleeves of a garment.

Quarter-square triangles: Formed by joining two half-square triangle blocks with a diagonal seam stitched from the opposite corners of the first seams, and then cutting the blocks apart on that diagonal to yield four quarter-square triangles.

Quilt: The result of fabric and batting layered together and stitched or tied to hold the layers together.

Quilt frame: A frame or hoop to which a quilt is attached for quilting the layers together.

Quilt label: A label that is usually attached to the back of a quilt to identify the quilter, date, occasion, and/or other pertinent information.

Quilt sandwich: The quilt top, batting, and backing—layers that make up a quilt.

Quilting: The process of piecing fabrics together to make a quilt.

Reader/writer box: hardware that makes it possible to read embroidery designs in one format and convert them into a different format which can be read by the embroidery machine or computer. Also offers the ability to save designs onto a card that can be inserted directly into the embroidery machine.

Registration: the alignment of various portions of a design to form the final embroidered design.

Regular cone thread: a 2-ply, cross-wound cone thread. Regular cone thread is finer and not as bulky when used in the interlocking loopers and needle threads of a serger.

Release lever: a lever specific to the Baby Lock® serger with Jet-Air Threading™ which releases the Machine Lock Button, opening the tubular loopers so the thread flows freely through the loopers as you serge.

Ribbing: Knit fabric used to finish the neckline, waist, and wrists of garments.

Right side: Side of fabric that shows on the outside. With printed fabrics, the design is printed on the right side. With napped fabrics, the nap is pronounced on the right side.

Rod pocket: A tube fastened to the top of a quilt back to fit a rod or hanger that will hold a quilted hanging on the wall.

Rolled edge: the narrowest 2- or 3-thread stitch. Created by loosening the needle thread and tightening the lower looper for a 3-thread rolled edge. When the lower looper thread is tightened, it wraps the upper looper thread around the edge of the fabric. For a 2-thread rolled edge, the needle thread is tightened and the lower looper tension is loosened, wrapping the lower looper around the edge of the fabric. A Two Thread Converter is necessary for a 2-thread rolled edge.

Rotary cutter: Special fabric cutting tool that looks and works like a pizza cutter. Used in combination with a special cutting mat and gridded ruler, it is used to cut one or more layers of fabric accurately.

Rotary cutter and mat: A sharp cutting tool with a rotary blade used in combination with a straight edge quilting ruler and self-healing mat to cut quilt fabric, strips, blocks, and so forth, during the quilting process. Cut through one or more layers of fabric with ease.

Safety stitch: also referred to as a back-up stitch. An additional stitch which is sewn with one of the needle threads (the fourth thread in a 3/4 thread stitch or the chain stitch in a 5- or 6-thread stitch).

Sample cloth: prestiffened muslin often used to pretest an embroidery design's stitch density, colors, and placement. Back the muslin with the same stabilizer you plan to use on your project.

Sashing: The strips of fabric, plain or pieced, used between blocks to increase size, separate designs, add color, and give the quilt pizzazz.

Satin stitch: a closely spaced zigzag stitch sometimes used to fill or outline embroidery sections.

Scaling: changing the size of a design.

Scalloped edging: a decorative stitch that is achieved by serging a narrow 3-thread overlock and then stitching over it with a mirrored blind hem on a conventional sewing machine. It forms a scalloped edge—a nice finish on the edge of a lightweight project such as a receiving blanket.

Scallop shears: Shears with special blades that cut a rounded scalloped edge on fabric.

Scarf: the indentation on the back of a needle, just above the eye, which holds the thread during stitch formation.

Scissors: Cutting tools with blades less than 6” long and have identical handle bows for the finger and thumb. Scissors are perfect for trimming, clipping, and crafts.

Seam allowance: The distance from the stitching line to the cut edge of seamed fabrics. The most common seam allowance for quilting is 1/4”.

Seam finish: a stitching method used to prevent the edges of a seam from raveling. Examples include overcasting or overlocking the edge.

Seam ripper: Used for removing stitching mistakes. A seam ripper has a special sharp point that slides under and cuts the thread.

Seam roll: Pressing tool used to press open seams. The rounded surface of a seam roll prevents the imprint of the seam edges from showing on the right side of the fabric. You can make a seam roll by tightly rolling and taping a magazine and covering it with fabric or a terry towel.

Seam sealant: a product such as Fray Check™ or FrayBlock™ used to seal thread ends to keep a seam from unraveling.

Seamline: Stitching line followed when sewing a seam. On pattern pieces, it usually appears as a broken line inside the solid cutting line.

Selvages: The woven edges on fabric, running the length of the fabric, parallel to the lengthwise grainline.

Serged seams: Seams stitched on a serger with a 3 thread or 3/4-thread overlock stitch.

Serger: Special sewing machine that uses three, four, or more threads instead of the two threads used on a conventional sewing machine. It stitches a seam, finishes the raw edges, and cuts off excess fabric all at the same time.

Serger patchwork: using the serger to sew pieces or stratas together for quilting.

Serger piping: piping created with thread by serging a rolled edge on bias cut tricot. Using a decorative thread gives more definition to the piping.

Setting Triangles: Used to complete the outer edges of quilt blocks that have been set on-point.

Shades: Colors to which black has been added in varying degrees.

Shank: Wrapped thread that connects a button to a project. Button shanks make it possible for the buttonhole placket to fit under buttons without puckering.

Sharpening stone: Tool used to sharpen shears and scissors periodically to ensure clean-cut edges.

Shears: Cutting tools with blades longer than 6” and different-sized handle bows or loops (a small loop for the thumb and a larger loop for two or more fingers). Shears are perfect for cutting out fabric.

(Six) 6” hem gauge: Sewing gauge with a double-pointed slide to guide in marking hems, pleats buttons, and buttonhole placements. The sliding pointer makes it easy to get even measurements.

Sleeve board: Pressing tool with a free arm for pressing small openings and hard to reach areas such as sleeves and pant legs.

Software: computer programs, CDs, memory cards, or disks used in the embroidery process.

Squaring: The process of using a square ruler or T-square on quilts or quilt blocks to make sure they are the same measurement vertically, horizontally, and diagonally.

Stabilizer: a material used to support the fabric and improve stitch quality during machine embroidery. Stabilizers are available in a variety of weights in cut-away, wash-away, and tear-away forms, as well as in liquid form.

Stash: A term used to describe a sewer's fabric collection.

Stencil cutter tool: a heated tool, originally designed for cutting templates, that is useful for removing excess synthetic fabric from the outer edges of embroideries stitched onto a fabric such as organza or nylon tulle. A Stencil Cutter can be used to produce clean edges on an appliqué or three-dimensional embroidery.

Stencils: Designs that are usually die cut in plastic template material and traced onto a quilt or blocks before stitching.

Stitch count: the number of individual stitches in an embroidery design.

Stitch finger: a small metal prong on the presser foot or throat plate. The stitches form on this prong when serging.

Stitch in the ditch: Stitching in the well or groove of a seam on the right side of the project, through all thicknesses to secure sections and keep them in place.

Stitch out: a design that has been embroidered onto a fabric as a test of the actual design.

Strata: Fabric strips sewn together in the piecing process.

Strip piecing: A timesaving quilting method involving sewing strips together into strata and then cutting them into sections instead of cutting and sewing each small piece for a section separately.

Tape measure: Tape used for larger measurements such as measuring fabric grainline and determining pattern size. Choose a 60” long tape made of durable, nonstretching material with metal or plastic on the ends to prevent fraying. Some tape measures have markings on both sides in metric and American measurements.

Tear-away stabilizer: a stabilizer that can be removed from fabric by carefully tearing the stabilizer from around the design after embroidery is completed. Appropriate for dense stitching where tearing won't distort stitches or the fabric.

Templates: clear plastic, paper, or fabric guides that include the outline of an embroidery design and are used to aid in positioning designs prior to embroidering them.

Tension: the tightness or looseness of the needle and bobbin threads during stitching or embroidery.

Test swatch: Small square of fusible interfacing and fabric used to determine the suitability and fusing time required for your selected fabric and interfacing.

Thread: All-purpose thread made of cotton-covered polyester or 100% polyester is the type most often used for machine sewing. Available in a wide variety of colors this thread works with all types of fabrics for all-purpose sewing.

Thread chain: the chain formed by overlocked threads in back of the presser foot when serging with no fabric underneath.

Thread net: a mesh plastic net used to cover serger cones and spools during serging to prevent the thread from coming off too fast and pooling around the spools. Especially helpful when using slippery threads such as rayon.

Tint: A color to which white has been added in varying degrees.

Topping: a stabilizer placed on the top of a fabric during machine embroidery, generally to prevent stitches from sinking into the base fabric.

Topstitch: Decorative straight stitch a uniform distance from an edge on the right side of fabric.

Trace, or “walk-about”: a machine feature that identifies the stitching area of the selected design within a hoop, as well as the center of the embroidery area.

Tracing wheel and paper: Tools used to transfer pattern marks to fabric. Tracing wheels may have pointed (serrated) or smooth edges. Serrated edges make a dotted line, but may leave holds in the pattern. Smooth edges make a solid line, which puts more marks on the fabric. Tracing paper is specially designed for use with tracing wheels on fabric.

Transfer: the ability to move an embroidery design from one piece of hardware or software to another using a cable.

Trimming: Reducing the width of a stitched seam to eliminate bulk.

Tubular loopers: tubular loopers specific to Baby Lock® machines with Jet-Air Threading™. When the loopers are closed for threading they form a tube to the eye of the looper, making threading easier and preventing threads from tangling.

Two thread converter: a spring type mechanism that fits in a small hole at the top of the upper looper. It “tricks” the upper looper into thinking it is threaded so that two threads (needle and lower looper) can be used for a specific stitch. Also referred to as Auxiliary Looper and Subsidiary Looper.

Tying: An option for quilting the layers of a quilt together. Usually yarn or floss is used to tie a quilt at intervals or between blocks.

Unbacked fusible web: Fusible web with no backing. Often used for fusing hems and appliqués.

Understitch: Pressing seam allowances toward a facing or under collar, then stitching close to the seams on the facing to prevent the facing from rolling to the right side.

Universal point needles: All-purpose sewing machine needles used for general sewing on knit and woven fabrics.

Under looper thread: Second or third thread from the right on a serger. This thread does not pass through the fabric. Instead, it passes over the surface of the fabric, catching the needle thread on the left and the lower looper thread on the right.

Value: The lightness or darkness of a color.

Walking Foot: Used to feed fabrics evenly when sewing multiple fabric layers. The teeth on the bottom of a walking foot firmly feed the top fabric precisely as the feed dogs move the bottom layer to eliminate shifting.

Wash-away stabilizer: a stabilizer designed for washable fabrics. Can be easily removed by spraying or immersing in water, leaving no visible residue.

Water-activated adhesive stabilizer: a stabilizer that becomes sticky when a small amount of water is applied to its surface.

Water- or air-soluble marking pens: Marking tools used to transfer pattern markings to fabric. The marks from water-soluble pens will disappear after being washed; the marks from air-soluble pens will disappear within 12 to 48 hours, depending upon the humidity in the air.

Wave stitch: a decorative 3-thread overlock serger stitch exclusive to Baby Lock® sergers in which the upper looper thread is alternately pulled and released while serging to form a wavy stitch.

Wide stitch: a stitch length of approximately 7.5 mm from the left needle or 5.0 mm from the right needle.

Window technique: Positioning an item for embroidery by positioning it on top of a hooped adhesive surface. Ideal for napped fabrics, fabrics on which hooping might leave an impression, and items too small to hoop.

Woolly nylon: a texturized nylon thread. When pulled it looks like regular thread; when allowed to relax it “fluffs up” or fills in the stitches.

Woven fabric: Fabric made by interlacing threads over and under one another. Examples of woven fabrics include denim, corduroy, muslin, and broadcloth.

Wrapped corners: a technique developed by Nancy Zieman to get sharp points on collars and other corners. Instead of stitching or serging around a corner in a continuous motion, one edge is serged first, then wrapped or folded toward the next corner before continuing to serge.

Wrong side: Side of fabric that doesn't show; faces the inside. On printed fabrics, the unprinted side is the wrong side. On napped fabrics, the nap is less pronounced on the wrong side.

Submit a sewing, quilting, embroidery, or serging term that begins with the letter “X”.

Yardage: Amount of fabric needed to complete a project. Fabric is measured in yards or meters.

Zipper: a fastener made of two rows of protruding teeth that are interlocked by means of a sliding tab, linking the rows together.
