I used about 45 feet of orange paracord, from Going Gear, to make this cow hitched paracord sleeve, to cover/carry/protect a 750ml(26oz) aluminum water bottle.
A couple of feet of paracord were used for the cinch cord with a lanyard knot and a cord lock, and about 43 feet of cord for the hitching to cover the bottle. A needle and some thread were used to further secure the cord at the start and finish of the knot work. More or less paracord may be used, depending on how tight/loose/close together the hitches are done. The cow hitching used a bit more cord than the half hitching did with another water bottle sleeve I tied.
A previous blog post has a photo collage, that I made, showing how to start the cow hitching. The last couple of photos in the collage show two different starting methods, one with the cord tied to itself to start for a permanent covering, and the other with a separate cinch cord and cord lock for a removable sleeve.
