Once the quilt top is finished it usually comes as a complete surprise to me that it needs a back too. You would think I would know by now. I am really trying to pare down my stash, so I try to make the back from leftovers from the top plus anything else that works well. If it weren't for the too-large stash, I would prefer to just buy a wide back for each quilt, and then I could get along with quilting it and then making another top.
