Laying out the 225 squares in a spectrum pattern

Now that all the squares are finished, it is time to sew them together to make the center of the quilt. Here they are (progressively) as I lay them out on our bed. Buster decided to help at the very beginning.







In the last two pictures, you can see the number tags on each block, just to keep me from screwing up the design while I sew it together. For a few hours today, I thought I had lost a block but I found it when I pinned all the tags to each individual block. Whew!
