It's happened many times. Sometime I will redo offending block, but the worst reaction I have had to date, (thank goodness). Was to through the entire quilt away. How I regret that action. Someone once told me there are no perfect people and certainly, no perfect quilts. Only The Devine is perfect. I now look at my mistakes a little differently, (but, honestly) they still agitate me a little! I'm working on my attitude a little closer now.
