I've been plugging away, and have the center assembled now. 3x4 in my case. I mulled over the border design, since I have to adjust slightly for the smaller center. I was going to add 4 inches of solid border before the pieced, but I had an inspiration the other day and by simply reversing the 2 pieces in the pieced border and using half-blocks on the ends, I can make it fit with only the 2" border that the original design called for. It changes the design in the corners a bit, and I have to re-make my 4 corner blocks. But heck, I already have to make 20 more border blocks anyway.
I hope to have something to show for all this work next week.
