I decided to go ahead and put a few pieces together to see what color I wanted to go around the squares. I made these 2 inch squares and I think they are still a little to big - maybe 1/4 of an inch. I think I like the middle yellow and the dark green the best. Once I get going and take my time it will look like catherdal windows. I think I need to make another design. My poor head hurts trying to think of someting that will be great.
