I was talking to a couple friends who have been quilting with a group for quite a few years. Recently they realized that they make a lot more money raffling quilts as opposed to auctioning them off. At an auction they would be lucky to get $100.00 for a quilt, but when raffled (with other items, but the quilt the main prize), they made $500.00 plus.
Raffle tickets can be sold to people outside the guild, where as an auction is only available to those who are there at the time.
