We just had a guild quilt show in June that made our guild a nice bit of money. Our tea/lunch room was a big money maker (over $1000 for a two day show) and so was our raffle prize table. Tickets were $2 and the prizes were donated by members and businesses in the community. Make sure the prizes are not all quilt related as many people who attend the show are not quilters but will buy tickets if the table includes other things (dinner for two at a local restaurant, a couple of rounds of golf etc). Our carefully stitched lovely quilted "things" sold very poorly. Our fabric was current, the quality excellent, prices were reasonable and still no one seemed to want table runners, aprons, burp pads, bibs etc. Next time we are not stitching anything for a boutique! Good luck with your fundraising as it isn't an easy thing for a guild.
