I am sure between the time,love and labor that was put into this quilt should account for something donated or not. The understanding was that it be made for a certain purpose. To be sold for auction to the public. Which means not having to be sold back to the maker. I bet the quilt will surprise you and sell quite easily.Should it not, then you should be able to take your project back and do with it as you please. Perhaps a fundraiser in the future for the guild will give you the opportunity to use your offering again.I don't think you should be penalized and that is what it is straight out if your quilt does not sell. Something bought cheaply at a store to donate is another story. Sewing a quilt is a whole different ballgame folks.
