I'm working on the Branching Rib Pullover from Creative Knitting magazine. It's not going very fast because the yarn I'm using is DK-weight (for non-knitters, that means it's really thin). I'm getting semi close to finishing the back, so I thought I'd post some update pictures.
This is an overall view. It gives you an idea of how far along I am.
And this is a closeup of the rib stitch. I think it's a really neat stitch. It also is fun to knit which is a huge advantage in a project of this size.
