1. Use a pencil or permanent marker to draw a diagonal line, from corner to corner,

on the reverse side of each 3-7/8" light square.

 

 

2. Align a light square with a dark square, right sides together.

3. Sew a seam exactly 1/4" from each side of the center line. Cut apart on the center line,

then press units open. Each should measure exactly 3-1/2" square. If you started out with

oversized squares, trim the units back to measure 3-1/2", keeping the diagonal line centered.

 

4. Now join triangle units together to form rows like this:
