The Non Slip Loop Knot. Superb. The strongest loop knot you can tie. Used by big game anglers worldwide. Easy to tie, far stronger and more reliable than the old fashioned strangulating figure eight knot that can substantially weaken line. Ultimate Knots
Another pinner said: Scout survival brackets! There are many ways to make them and with all kinds of colors. This is another thing that we did at Cub Scout Day Camp this year. Not one complaint. Well.... maybe one or two because they wanted to make more than just one lol.
