I'm gonna note this calculation and keep it with my twister ruler.. Holy cow..You lost me at hello !!!!!
After that, I cut them, and ended up with 49-8" blocks. Finish size 7 1/2".
So, if I do 7 x 8 = 56 plus border, I should end up with 8 x 9 = 72 8" blocks (7 1/2" finish) yeilding 60 x 72...I add my 6" border, and I should have 72" x 84".
I'm WRONG! Here I'm saying that the blocks are 7 1/2" finish, yet I'm calculating them at 8" finish. URGH! Sometimes I strongly dislike math.
7 1/2" x 8 = 60" + 12" border (6" on each side) = 72"
7 1/2" x 9 = 67 1/2" + 12" = 79 1/2"
72" x 79 1/2" ~ NOT big enough.
So, I'm going to start with 72 - 10" blocks. That should give me:
7 1/2" x 9 = 67 1/2" +12" = 79 1/2"
7 1/2" x 10 = 75" + 12" = 87"
79 1/2" x 87" = BIG ENOUGH! Actually, perfect!
Thanks for everyone's help. I just needed to think this through. :)

But I still don't get the 7.5" finished if your 1st quilt top finished at 61".
Wouldn't the block center portion have to be 49"x49" (which means 7x7 layout at 7" finished) + 6" border = 61".
It's not important but those little things drive me crazy.
I'm not exactly sure about the 61" x 61". That's what the pattern said it was supposed to be. I hadn't had it done yet, so I didn't know for sure.
The ruler is 8". So, yeah...I don't know.
I'm just know that I'm going to do 8 x 9!
Thanks again!
