Multicolored Crochet Sweater

Tonight I totally obsessed over a new sweater I'm crocheting. Eventually my hands gave out and the clock passed midnight, so I had to set it aside. I was going to use a pattern in a vintage crochet book, but I couldn't make heads or tails out of it.  So I'm duplicating it based on how I think she did it. That could be a disaster. But at least I'm enjoying the process. It's mostly shades of purple and gray.
