Below are a few half hitch creations of mine beginning with the can koozie. I made the hitching for this item very dense and it insulates quite well. To be exact, it contains 350 half hitches and a pewter skull on the draw string for a finishing touch.
Next is a similar item I made for a water bottle. Not much different here with the exception of the two tone look by adding the black cord towards the bottom.
This is just an example of a less dense hitching pattern. This works well for wine bottles too.
This one is a cool touch for a candle or a pen/pencil holder for your desk.
