I wanted to give a quick update. I have finally finished the back and both sleeves of my hoodie. The back stayed neglected for quite some time because I was determined to try the short row shaping technique to leave live stitches at both shoulders so that I can do a 3 needle bind off for both shoulders. Some of you that completed your hoodies mentioned this, and I was intrigued! I am familiar with short row shaping for sock heels, but hadn't done this on a larger garment. The technique works great to avoid that "stair step" jagged look of binding off stitches at the ends of several rows (as suggested in the pattern).
For anyone that wants to try this, I suggest the following articles:
One from knitty
A great one from Nona Knits (she actually compares 3 different methods).
If neither of those works for you, Google "short row shoulders", and you'll find lots of help.
The basic idea, for those who haven't tried it, is that you have to wrap one stitch before you finish knitting or purling all the stitches on that row; this leaves a gap between stitches, which you will later go back to close up and make invisible. Easier if you try it...trust me :)
Here's a quick shot of the finished product, ready and waiting to be attached to the front pieces (which are now in progress).
