This was in the lot of items I bought yesterday. I bought a quilters stash and am slowly going through it. This one confuses me. I think it's like a yard of fabric. The selvage reads Redwork Romance by Alex Anderson by P & B. Are you supposed to actually do redwork embroidery over the blue designs? Does the blue wash out? What are the little blue flowers on each design for? They must be some kind of alignment tool? I'm sorry, but this one confuses me! Can someone tell me what this fabric is used for?
