Melissa, that sounds wonderful what you've picked out. I'm wondering, with 9 blocks, that would make your quilt square, right? If you do 12 blcoks, it would make a rectangular quilt. What if, you took one of the blocks, and made 4 blocks, and put one on each outside corner? That's just if you would like it rectangular. If you do 12" blocks, you would do 3 blocks by 4 blocks, and if you do a 2" sashing between all blocks, and for a border, your quilt would measure 44 x 58, i think :)
