Tonight I thought I'd try to finish up a UFO that I started back in Dec. I decided to use some ratcheted clamps I just got a few weeks ago and clamp the backing to my dining room table. I clamped each layer together and pinned it.
Boy, what a back saver!! :-D Not only did it work, but I didn't have to get down on the floor to sandwich it!
This is what it looks like. I got 4 of them at home depot in the tool dept. They run about $6 each.
