I like a good I-cord bind off, and have used the technique quite a bit, most lately in my Kenneth Street Slippers and in my upcoming Octopus Slippers. (They’ll be out March 17; I’ll update this post with a link when there’s something to link to. In the meantime, here’s a sneak preview, showing the grafted bind off.)
One of the things I like about this bind off is that you can graft it closed, making an almost invisible join. I’ve been meaning to draw a tutorial showing how to do this graft for a while; the new pattern seems like a perfect opportunity. So here’s how I do it:
After all project stitches are bound off and only the I-cord stitches remain, slip stitches back to the left needle. (If using DPNs or a short circular needle, simply slide the stitches to the other end.) Cut yarn, leaving a tail about 8 in/20 cm long. Thread tail onto a yarn needle and bring to the right-hand side of the stitches.
Bring yarn through the first stitch purlwise.
Bring yarn behind the legs of the corresponding stitch in the cable cast on at the beginning of the I-cord: if your first stitch in Step 1 is next to the wrong side of the fabric, the corresponding stitch at the beginning of the I-cord is also the one next to the wrong side.
Bring yarn through the first stitch on the left needle, knitwise.
Slide first stitch off the left needle and tighten the new graft stitch so that the new stitch matches the I-cord bind off stitches.
Repeat steps 1-4 for remaining I-cord stitches. Weave in the end to secure it.
