I stopped to take a breath at the heel, and just assume that after the gussets they'll fly along again.
I really like this yarn, and although my needles could be pointier, this is simply a delightful knit. The colours are just wonderfully mossy and murky, subtly changing, and the yarn is soft and not splitty.

Carry on. One square brown, one half-white, half-black, one darker brown, one more half-and-half.
On the last square, you have to pick up a stitch as you meet the bottom of the first square, and knit this together with your last stitch.
Make a bunch and sew them all together -- over time!
Although I am certainly not in need of any more projects, I have joined a group on Ravelry to knit vests in February. I have a pattern, I have yarn, and I think they will work together. We'll just see if I am crazy enough to cast on for this!
