I used a 30 foot length of orange paracord, with a couple of feet of black reflective paracord for the cinch cord with a cord lock, to make this paracord pouch/can koozie with vertical half hitching.
The vertical half hitching is almost the same as regular half hitching, but you hitch around the previous hitch instead of the cord between the hitches, which makes the vertical columns with the cord stretched between them. It makes a snug fit around a soda/beer can as a koozie, and also is a good fit as a pouch for my LED lantern. This was another example of various hitching techniques, shown in 'Creative Ropecraft' by Stuart Grainger.
My friend, Manny, emailed me about checking page 108 of 'The Marlinspike Sailor' by Hervey Garrett Smith, for a reference of the hitching. I checked my copy and sure enough there's a drawing of a water jug covered with the same type of hitching and a description of the process, but Smith calls it 'French Hitching' in his book, where I'm more familiar with that name applied to a spiraling/twist type of hitching knot work.
In an older Smith book, 'The Arts of the Sailor', it's referred to as fender hitching, because of its use in making boat fenders. Another example of knot work going by different names, which can get a bit confusing sometimes.
