How to: The I-Cord Bind Off
This bind off method leaves a clean, corded edging on your knitting. It adds a subtle, decorative air to the piece. Try it on sweater bottoms, purses, or even in felting.
Knit two stitches and slip the third stitch knitwise.
Knit one more stitch. You will now have 4 stitches on your right needle.
Use your left needle tip to pass the slipped stitch over the last knitted stitch. This will leave you with three stitches on your right needle.
Slip these three stitches back onto the left needle tip, purlwise. Tug on the working yarn to tighten up the stitches.
Repeat Steps One through Four until all stitches have been bound off.
