1. From each of 2 fabrics, cut 1 square 7⁄8" larger than the desired finished size of the triangle-square. For example, to make a triangle-square that will finish 4", cut 47⁄8" squares.

2. On wrong side of lighter square, place the Quarter Inch Seam Marker diagonally across the square, with the yellow center line positioned exactly at opposite corners. Mark stitching lines along both sides of the Quarter Inch Seam Marker (Photo A).

3. Place light square atop darker square, right sides facing; stitch along both marked sewing lines.

4. Cut between rows of stitching to make 2 trianglesquares (Photo B).
