I forgot to mention. In my pic 2, I show two line on the sq. When I sew a 1/2 square block, I usually make a line 1/2" away from the 1st line and sew on both lines. I then cut between both line 1/4" and have the 1/2 square I want and a smaller square to use for making a small wallhanging or potholder. I plan to make a pot holder with my left over squares this time. Happy sewing everyone.
