The only thing I can complain about this is our blocks have to be prewashed....I never prewash anything. That means not only do I have to prewash my blocks but the fabrics I will be sewing snowmen, doggie scarves, their tennis shoes and hats and bathing suits (oh wait...I forgot, snowmen don't wear bathing suits)....but you get the picture. Or can I make up my blocks and then wash the whole thing when done....that would work. I could make them 13 inches to allow for shrinkage or maybe 14 and cut them 12 1/2 " afterwards for completed block. Darn, I'm smart.
