To make the center unit place a Color 1 3-1/2" square lined up with the upper left corner of a Color 2 6-1/2"
square, right sides together. On the back of the top small square draw the diagonal. Sew
ON this diagonal line. Trim off excess seam allowance, pressing the remainder towards the
outer triangle. Repeat this with another Color 1 square on the opposing corner. Repeat
again with two more Color 1 squares on the other two corners, pressing those seam
allowances towards the center square...
