My quilt guild recently had Marguerita McManus present for our program. She does a QAYG method thatis very easy to do. She showed some of her quilts where she bought the blocks on ebay, or such, reset them and then did QAYG with her method. We all laughed with her. The quilts were very nice looking.
She has YouTube videos that explain it all. Just type in "Marguerita Mcmanus youtube" and you will get there. There are 8 consecutive videos in the main one you look at.
