Rainbow in progress!

I'm finally getting closed to finished with my rainbow spectrum afghan.  It includes 49 squares with every color of the rainbow matched up with every other color.  I knitted all the squares for this while I was in Hawaii way back in August, so its about time I finish it up.  The last 4 squares are blocking at the moment, and I've joined the first few rows. I hope to get it completely finished and on the shop tomorrow!
