This happened to me once when I was following a pattern out of a book. I got so frustrated I was about the throw the whole thing out. My DH came in to see what the ruckus was about and studied the pattern to figure out one of the blocks in the book was wrong. Hurray, it wasn't me this time!! Anyway, I fixed it and the quilt came out really pretty. It was my first drunkard's path. hey maybe that explains why the block was wrong! It really was a "drunkard's path"
