I have a panel in my stash that is so bad I can't believe they ever really intended the top square to be square! The rest of the designs in the panel look square and work together but that top one is just really off in one corner. I've tried the diagonal tug on the corners like I was taught in my 1972 home ec class but that wasn't enough. I haven't washed it yet, sometimes that helps the wonky factor and other times it makes it worse. Fortunately for me it's only going into a pieced quilt back if it makes it there at all.
