Step 2. Use your ruler to draw a diagonal line on the wrong side of the fabric.
It isn't necessary to draw the quarter inch lines on each side of the center line, but I like the reference lines to sew on.
Step 3. Sew a 1/4 inch seam on each side of the center line.
Chain sew down each side and clip apart.
Step 4. Using your ruler again, cut down the center of each square, creating two triangles.

Trim the top and side, rotate, and repeat. The finished unit will measure to be a 3 1/2 inch square.
