What I find very interesting about this pattern is that depending on what your 9 patch squares look like, you can vary the look of the pattern. Since the charm pack has all different squares of fabric, my quilt is very "scrappy" looking. If you use traditional color choices for a 9 patch, you get a distinctive pattern after you quarter the blocks and resew them. Here are some examples from Google Images.
I will definitely try this pattern again with a larger end result. I only had one charm pack of this particular fabric. Don't know who is getting this one yet.
