I agree that #1 would make me crazy if the blocks didn't line up - I like #4 too but not with black OR maybe I'll listen to DH and just put on a binding. If I don't add a border, I'll add another row of blocks to make it a bit larger.
NOW what are your suggestions for quilting? I was thinking of taking it to be quilted in some all-over pattern the quilter would suggest since I've never done that before or SID and tie it.
Thanks -
