What a find! I don't know what you would do with it, as I am not much of an imagination person. I have a bag of OLD pieces too. Got them in a mix I picked at a Yard Sale. Don't know what to do with them either. Looks like someone took the quilt top apart and tried to replace pieces that were too worn and decided to remake some of the pieces so the colors would match. I'll start a thread one day soon and post it to show you. I'll be looking for some ideas.
