I couldn't see the mistake block, but that is okay, the Amish have a policy, to always make one mistake in every one of the beautiful quilts they make. The policy being, is that only God is perfect, so they make sure none of their quilts are. They make one block wrong, or have one piece of fabric, wrong side up, and so on...... Yours is beautiful, and perfect in my eyes. Thanks for posting. Auntie B.
