My guild (approximately 250 members) collects $35/year dues, but the bulk of the funds come from a quilt show every 2 years. They charge admission to the show, have their own booth at the show where they sell donated items, and sell food at the show, and raffle a quilt made by the guild members. The guild also makes and donates a LOT of quilts to Ronald McDonald House and Shriner Children's Hospital. I believe a lot of the fabric for the donation quilts is acquired from estate donations or member stashes.
