I have 7 blocks done, 6 more to do.

I'm working on SuZQ's Tossed 9 Patch block. I've made it as in the pattern by cutting my squares 5" square, sewn 9 patchs together then cut in half in center both directions, tossed 2 squares and sewn 4 blocks together. I end up with a block of 13 1/2".
Can someone help me please? Which size do I need to cut my 9 patches in order to obtain a 12 1/2" square? I'm going bald here by tearing my hairs LOL
Thanks!
LOVE & HUGS
