Well, here is my Step 4 blocks. I'm doing yellow instead of the red. I had to round up more yellow to do my blocks so I'm alittle behind, but I"ll catch up this weekend. I purchase some squares on Ebay, and did some swaps with a couple of people on another board (as I can't do that here) and I have enough yellow now to finish my blocks. I am very pleased with the way this is turning out.
