Omg. It's like I was in your head of something haha, I like just decided I wanted to make an afghan in two colors of all different granny squares. I just decided this maybe two days ago. This is fantastic and looks so warm!
That is funny! Now you have more incentive to do it, since it can be done! Good luck, I'd like to see yours when it's done. I don't know if I'd do another one or not, I always get tired of making squares.....
