In small cord, that makes a dandy knot for a lanyard, especially if you already know how to tie one. Tie one smartly in one end, the use the standing part (the part that would go over the limb in a real hanging) to tie another one. Adjust them both so the coils slide along that Standing Part “backbone”…
This makes what Roy called “Sister Loops”, which — if made the right size — can give you something to attach Paracord to… Best of all they are cheap to re-make when you need new ones.
Adjust the cordage so the loops are the “right” size, tighten all the coils and trim the ends — ta-daaaa! (“Right”, of course, being whatever size you want… YMMV and all that…)
By using two “hangman’s nooses”, the size of the loops is adjusted by sliding the coils along that “backbone” part, which means you can have two “medium” loops or one “big” and one “little” loop, with the coils jammed together, or two “little” loops with the coils apart and a single cord between them. Good idea!
If you don’t want the coils spreading apart, tie a two-strand Matthew Walker knot instead of the above, and you’ll have two loops which trade cord/size but have only a small set of coils between them.
Sorry, that’s probably TMI…
If you know how to make a double overhand knot, in the end of a cord, around “something”, let that “something” be the rest of the cord, folded in half, and you’ll notice that same slipping loop, but a lot easier to tie. Just fold the cord, take it in your hand, then use an end to tie a binding knot around the parts coming out of your hand. Repeat “going the other way”. It takes doing it, checking what you’ve done, adjusting adapting & re-doing it at least a few times, even for the Masters (less, but it happens); so don’t worry if it seems hard, that’s what makes it great.
More TMI: Do your sister hangman’s nooses on a piece of thin cord 18” or more long, right at the ends. Now “hang” the ends of the temple pieces of your sunglasses… Some fun these knots, eh? If you work aloft, that last trick will make dandy safety lanyards for your tools. Just “hang” your wrist with one end, the tool with the other and Bob’s yer Uncle! No droppies!
