Now sew the ends.
You want one end sewn just once so you can wrap it around the D-rings and sew it there a couple of times. It is quite thick so it can be tricky.
For the other end sew it several times.
So I post this with some chagrin. While I was making this up, Ashley from Make It and Love It posted a bunch of brilliant braided knit projects. She even has a great 5-braid technique that I want to try next time. Be sure to check her out.
Instead of hand stitching the little knot cover up, I machine sewed it.
Just trim and wiggle it right side out.
