The original suggestion was for a black and white photo. That thread is called "When to Call it Quits (or How Batik HSTs Kicked My Butt)".
My sewing room is my dining room which is attached to the piano studio where I teach 22 private piano lessons. Can't leave things too spread out or messed up. So ... spare bed is my "Design Wall" and I troop back and forth. Usually not a problem, but trying to keep him from seeing the very distinctive train fabric I'm working on IS a problem!
Pinning would have worked ... didn't think of that either. This is really the border - just blocks wide but about 16 blocks long and pattern must be exact. Problem solved now!
