I have a friend who bought the Fun and Done ruler/templates at the last quilt show we went to together. She made up a small runner out of it. I don't think she was overly impressed with it to be honest with you. She didn't seem all too thrilled about it when she was done. Her blocks did not come out evenly lined up and I think it frustrated her a bit. She didn't say much about it.
I'm going to borrow her templates after I move and give it a go... sadly I won't be able to give you any real feedback about it for at least a month. I will be very backlogged with projects after we move next week.
