My original thought when making these blocks would be to lay them out in color wheel order. However I will have to make a lot more blocks if I want to do that. I will need the ones that are a blend of yellow and orange, and a blend of orange and red, and a blend of red and purple, etc. I have only made 2 orange blocks so this trial layout isn't very successful, but I had to try it anyway. I wouldn't run the colors in straight rows either, I would have them on the diagonal or vertical and weaving in and out of each other.
