2" squares? That big? Wow!! I have completed seven 1 1/2" TATWs, and just finished making about a hundred 1 1/2" (yes, finished size) 9-patch blocks to set a Crazy/Crumb quilt I've been working on. I chuckled at your subject line, because the name of each of the TATWs is some version of "What Was I Thinking??" So, I feel your pain. Work at it for a bit, then on to something else, and go back to it as your patience allows. You'll be done in no time. Can't wait to see it, so be sure to post!
