We all make mistakes but that's how we learn so really it's a good thing for all of us out here to pay attention too these types of issues that come up. I am always trying to figure out how to get marks off of things. It just stinks when it happens to something you really like. Lot's of ladies marked their tops with regular pencils because that is all they had and those marks are still on those quilts. It gives it more character and tells a story. There is always a sunnyside to a mistake.
