Thanks all, yes I think I'll set it straight. I worked on it yesterday a few hours I think, it's hard to tell as in between I'm doing laundry, cooking dinner, talking to DH, kids etc... you know how it is! LOL PLus I had to do some unsewing because I wrote a couple of measurements down wrong - I had to change out 4 strips in my second set. The only real issue I think was cutting the sections from the joined strips, and mine were only 30" long and I have a 36" mat. In the full size one, cutting across 63" will be tricky. Perhaps it could be done in sections?
