Place a 2-1/2"
Color 1 square right sides together lined up with the upper left corner of a Color
3 4-1/2" square. On the back of the small square, mark the diagonal, and
sew ON this marked line. Cut off excess seam allowance and press the remainder towards the
small square. Repeat this with another Color 1 square on the opposing
and then on each of the two remaining corners. Trim this back to measure
4-1/2" if needed...
