SOAK to the rescue
Here is the sleeve of a new sweater I've been working on. The yarn I used was two strands of different greys. They weren't as soft as I would have liked, but it was such a pretty pattern in this yarn. So, SOAK to the rescue. I "soaked" the sleeves and the back/fronts (worked as one piece) for several days. I drained the excess water out of the sleeves and rolled them in towels. Then I pinned them out on my blocking grid. When they're dry, I'll block the remaining piece. Then I just have to sew in the sleeves and work the ribbing around the neck edge. I'll put a picture up of the sweater when it's finished.
