I just finished up part 1 of this system. I now have a copy paper box of squares - 2.5", 3.5", 4", 5", and a boxes of mini strips, 2.5" strips and 1.5" strips (I am going to build a postage stamp quilt). I have been collecting photos from your posts for ideas, and I can't wait to get my UFOs down so I can start up.
