A little tip to think about. Most of the quilt patterns I see assume that you will be cutting the fabric across the grain(not lengthwise). The cross grain S T R E T C H E S, and with a sandwich of top, batting and backing the result can be as much as a half of an inch difference in a 20 inch cut. I am currently working on a log cabin, all cut on the cross grain, and using the quilt as you piece technique which I love, but NEXT time I will give serious thought to cutting those strips on the length wise grain to minimize the stretch.
