Like Bill I've usually wrapped with paracord using the French knot (half hitches,) you can change direction by throwing them the other way, with 2 lines you can make a diamond pattern. However, recently I saw a method on another forum and used it on my 40" wheel. You catch each loop so you don't have to keep going around with all the line, seemed a little faster, still took a couple days and blisters. BTW I went right over the top of the old leather cover which was starting to develop holes from wear and torn stitching.
Also I put the braid up for a good grip, I was informed after the fact by my wife that was backwards. Should have put it inside, so check with the helmsperson as to their preference.
