These and the one up top are the Sean Scully pictures that inspired this blanket. Sorry about the blurry pics, but you get the idea.
I knitted the orange/yellow/white and purple/grey pieces separately. Then threaded onto a cable needle the orange/yellow/white and cable-cast on more in blue (one strand Malabrigo Buscando Azul and one some blue Cascade 220 left over from Husband's blanket). Then I knit back in the green. When the vertical green sections separated by thin blue stripes are done, I'll sew on the purple/grey piece. Not sure if I'll try to match up the stripes or not. I'm pretty much winging it.
