Well, I was going to suggest dying it, but obviously you are already on top of that!
I just got a Ram Wool magazine in the mail and they had a chunky turtleneck sweater in it that I liked. If you go on their website http://www.ramwools.com
and search for Ram Designs Simple Chunky Sweater. I don't know if you would be able to e-mail them for just the pattern or not. I think it is just in a kit. Anyway, it looks like the perfect sweater for that yarn! Can I be nosey and ask what you paid for that great find??
