My very first quilt instructor told me I had a wrong block in my quilt. Granted, it was a pinwheel ( I love pinwheels) which was not in the pattern, but, for Pete's sake, it's asampler quiit! I did not WANT another of the block that the pattern called for. It was a quilt to remind me of my Kansas childhood, and there are a lot of windmills on the KS prairie. The quilt told a story, and so I spoke up and said it's not wrong, it's exactly what I wanted. She taught me a lesson: don't TELL, ASK. Give the quilter a gracious out.
