I would consider that once I gave a quilt to an organization to be auctioned, it was no longer mine. If it sells for a lot, wonderful. If not, then I'd decide if I wanted to donate another $10 and get the quilt back that I had already given away or donate it to another charity. The last quilt I made for a charity auction was a small throw that was hand quilted. It went for $225 and I was pleased with that. A large quit that was machine quilted went for $1400!! And a hand pieced, hand quilted scrap quilt went for $600. So, you never can tell what people will bid on, but they don't look at the work or the investment of fabric, they just bid on what they think is pretty.
