At our quilt shows, we've done the food a couple of different ways. One time, when it was held at a church, the ladies auxilliary made & sold the food. Another time, when we our venue dropped out a month before the show date (YIKES!!), we contacted our local Subway sandwich place. They made "sack lunches" for us, with their small round bread sandwiches & a bag of chips in each. We were able to sell them for a small profit. And we gave the leftovers to all the guild members who helped on take down! :D
