I try to bring UFO's, unfinished objects. That way, some of them get done! LOL
My friend runs a retreat for us gals twice a year, and we agree before the retreat on a quilt pattern to all work on as well, or she will teach us a new pattern. On my first retreat with her I had packed SIX UFO's plus the fabric for the quilt she was going to teach us. I realized no way was I going to be able to do all that in 3 days!!! Over-reaching again! Or, maybe being optimistic. So, I brought 2 small projects and the one we were learning and that was just right. But, even if you bring more than you can work on, you can still have a show and tell with your projects. I hope you have fun!!!
