Ours is a relatively small guild, probably about 25 for the annual Xmas party. Last couple years they had it at a members house, but this year it was held at the church where we have our regular meetings.
We also do a potluck, play a round of Quilt Trivia w/fat quarters for winners (tho everyone gets one in the end); small gift exchange (under $10/wrapped) with the Mrs. Wright cookie story game. The last couple years they had everyone put down 10 things they wanted to accomplish over the next year and put it in a sealed envelope to be opened at the next year Xmas party. When these are opened & read, they had a small prize for the one who managed to accomplish everything on her list.
