When I make a quilt for donation I have learned to use a simple pattern in great colors. Usually it is made for Relay for Life. The team I donate it to sells raffle tickets and starts about 4 months ahead of time.
They never earn what they're worth but a few hundred dollars is more than I can donate.
I'm sure your quilts were worth more than they were sold for. Quilts don't seem to auction too well, do they :(
I'm sorry your feelings were hurt
