I just spent about 3 hours pin basting my Iron Quilter II entry. Had to take all the pins out the first time because I noticed there were some pretty bad pleats in the backing material. Repinned the backing fabric to the carpet and tried again. This time I avoided kneeling on the quilt and pinned from the center on out. Seems to have worked; no wrinkles in the back. I used a grapefruit spoon to close all the pins once I was done (and saw that the back looked good.) Tomorrow might be a good day to actually start the FQ on it. I stenciled a pattern on it, but some areas didn't come out very clearly. So I'll get creative when I come to them!
