A guild I belonged to in another city did a garage sale before and after one regular meeting each year. There was no charge for a table -- just a great opportunity to exchange. It was great fun! My current guild has a live auction once every two years as the program of the meeting. All proceeds are donated to the guild, and the money is usually used for speakers or our charity quilting. That also is great fun with tons of goodies sold, and one of our members acts as the auctioneer.
