I donate to auctions, but I always put a minimum price on my quilts. Frankly, usually that minimum price is the cost of the quilt (to me), including the proportionate cost of getting my machine gone over every year. I went from outright donating to putting a minimum price at my husbands insistence. I priced lap quilts (there were several and they were for a bus that takes children on tours) and I made the minimum at $70 each (if they didn't sell for that I wanted them back). The price put on them was $100 each and someone told the table "If no one else buys those for the bus kids I will buy them all." All five of them sold. I think the fact that I insisted on the minimum, after explaining abou the cost to me, the group realized they had real value. It was a win/win/win for me, the kids, and the group that needed the money.
