I put some Moku hitching(coxcombing) on the top section of this adjustable walking cane. The link shows half Moku hitching, but the instructions do mention how to do the full hitching.
I used two 20 foot lengths of cotton cord for the hitching, for about one foot or so of knotted length on the top curved section of the cane, and a few more feet for each of the 5 lead 4 bight 2 pass turks head knots that were tied over the start and finished ends of the hitching. I had to take a quick glance at my copy of 'Creative Ropecraft' to refresh my memory on the smaller turks head. Even simple knots aren't so simple if you can't remember how to tie them from lack of practice. I also used a few drops of super glue to secure the ends of the cotton cord. The cord came from the fishing tackle section at Walmart.
I could have used more cord to make it longer, but I didn't want to cover the adjustment holes on this particular cane. I've haven't applied anything like varnish to the cotton cord, but that could be done to extend the life of the knotwork and probably protect it from dirt, UV light, and staining over time. Paracord would also work well for this type of knot work, but inexpensive cotton and hemp type twisted lines have a nice look of their own.
