Can you tell? This challenge has really taken hold of my imagination! LOL
The only other way I could think of was the one illustrated below. If you start with 2 pieces measuring 4.5" x 4.5" you will end up with 2 patches measuring 4" x 4".
When sewn together, each block of 4 patches will measure 7.5" x 7.5" (which finishes to 7" x 7")
If that isn't what you're shooting for, please call your teacher and tell her to FedEx those instructions overnight! This question is driving me batty from curiosity. (I think I need a life! LOL)
:shock:
