Is there a knot tying event in your area?Please let us know about it.
I used to use the jug sling on water bottles, but found it a bit messy to deal with once it was tied. My new go to knot for water bottles and coffee, etc. (Starbucks to go cups) is the double fisherman's knot. I simply bend the ends together and separate the two knots far enough to insert the neck of the bottle or the upper portion of the tapered cup, and then pull the knots toward each other until the cup/bottle is held snugly and pick it up at the middle of the string.JP
