It has been a little while since I worked on this, but I finally got back to it. I had to do the math, which I was trying to avoid. Finally, I just did it.
That gave me a structure, so I started putting all the squares up. I had to redo the bottom left hand corner to add some greys that were hiding. I had to remove some duplicates. I still have to rearrange a bit to add more pink and a bunch of purples that came out of hiding as well. Still, I am making progress and will soon be able to put this piece together. YAY!
