I take way too much when I go on retreats. My fear is I'll run into an issue and won't have anything to work on. Or I'll get bored and want to work on something else. One year I took 4 quilts which just needed finishing up -- a few rows added or borders. Got them all done. Haven't done so well since then. This past year I only worked on one quilt -- I made setting blocks to go with my sampler blocks and started sewing the top together. I didn't get it finished, but it was close.
I try to get all the cutting done ahead of time if I'm working on a new project. I want mindless piecing so it's easy to pick up again after getting distracted by all that is going on around me.
