Ugly is as ugly does, but not always.
I made a OBW from the ugliest fabric I had ever seen. Brown with faded looking flowers. Just awful!!! Figured I'd give it to a daughter in-law as brown and faded is just her thing. Won a blue ribbon on it at the county fair. It's lovely and guess who's not getting a quilt?
You might be very surprised. Particularly with those nice big blocks, you can highlight it with a collage of template quilting patterns.
