In case you're curious, it's Cherry Tree Hill Supersock Merino in Indian Summer on size 2 bamboo DPNs.
The body is as long as I'd like it to be (although that's not in the picture. It's only about halfway done there.), and now I'm working on adding a strap that will cross my chest. I'm also adding a pocket on one side of the strap, that will be big enough to hold a credit card, ID and some cash. The strap itself will be linen stitch, and the pocket will be double knit St st. I'm using the *k1 sl1 w/ yf* method of double knitting, which I figured out and taught myself through trial and error. I've made several test runs, and the pocket itself is not a problem. However, because it's the width of the strap, I'm having trouble keeping the edges neat.
My question: Are there any tips or techniques that you've used or would use in double knitting to keep the edges neat?
