My favorite is the white elephant/gag gift party. My friends and I have been having one for over 20 years, and we have about 40 in attendance (not quilting themed). You could have everyone bring an ugly block, or a bizarre SM attachment or foot, or something along that line. I'd love to do an ugly block gag gift party! Then next year if they have used the block have them bring the project in and have a contest on who did the best job using their ugly.
