In KS we get around it by having "donation of " on the ticket--if someone requests one for free we do give one (only one). KS finally realized that most groups doing raffles are doing so for charity so they've eased the rules some too.
Our Guild makes anywhere from $800-1200 on yearly opportunity quilts--but that is selling tickets for about 8-10 months not just a one event thing. We do better with silent auctions if it's a one event effort.
