Finally finished this afghan, for me. I had no great plan, just wanted to do white to black, which I did more or less. (You can't see the black, there are about 2 more sections of panels behind the section on the far end of the couch.) If I would make one like this again, it would be a bit smaller, it has about 70 or so squares, and I would have made the solid colors in a knitting pattern that would give them visual interest, instead of large blocks of garter stitch. It is so warm. Folded double, I slept under it one night recently, and had NO need for extra blankets. However, it's also rather HEAVY. I guess that's why it's warm?
It's sort of ungainly, probably not the most carefully coordinated color combination, and maybe just a bit tacky, but hey, it fits me, and I like it, so... Meh.
Oh, and I didn't use the rest of the square because it was so large already, I am planning on making, and probably donating the one I make from those... Maybe... Heh.
