I noticed that no matter how carefully I thought I was laying out my Double Slice Layer Cake quilt, the same thing happened. Maybe while sewing blocks into rows, I switched something , liking it better, but not realizing that it was not going to co-ordinate with the row above/below. However, in the final analysis, I think that it just adds more interest to the whole picture and I am at peace with it. That's my story and I am stickin' to it.
