How-to: Make half-square triangles
Learn how to create triangles from fabric squares or, even easier, fabric strips.
Technique #1 using the Quick Quarter Ruler Set:
A set of two see-through plastic marking guides that are 1/2" wide with a center slot.
Cut quilt blocks. Place two blocks right side together.
Positon either the 8" or 12" Quick Quarter Ruler on point and mark on each side of the ruler. Also mark the center slotted opening.
Stitch on both of the outer stitching lines. Cut apart at center markings. Press.
Technique #2 using Tiger Tape:
Scant 1/2" wide reusable tape.
Cut one end of the tape to make a point. Place two same-size squares of fabric right sides together.
Put a strip of Tiger Tape diagonally across the fabric squares matching center line to points.
Sew along outside edge of tape on each side.
Cut down the center. Press.
Technique #3 using Thangles:
Thangles templates are made from easy-to-stitch-through paper in six sizes. You'll use fabric strips—not squares—to make half-square triangles.
Place fabric strips right sides together. Position a strip of Thangles on top. Note: Choose the correct size of Thangles for your fabric strip width.
Stitch along outside stitching lines.
Cut along the center line.
Press each square with paper in place. The paper prevents the fabric from stretching.
