I have found that quilts auctioned off via raffle tickets at a fundraiser bring in lots more money than an actual auction. I have several friends that make twin size quilts for various church/ charity fundraisers on an annual basis; raffle tickets are usual 1 for $5 or 5 for $20. Every quilt "auctioned" off that way has brought anywhere from $700 - $1200
that said, I agree with the previous poster of putting a "reserve" or base price on a quilt to be auctioned off. I think $100 is still a bargain even for a throw!
