Wine Table Topper

My son and his wife have a round copper-top table. (No Kids-yet). They entertain a lot. They asked if I could make them a quilted table topper. I have not figured out how to make a round quilt. So I made a square table topper with a bunge cord threaded under the binding with toggles. This was they can pull the cord and tighten on their table. The back is a beer print. Trying to please wine and beer lovers alike.
