Adjustable-Length Sliding Knot Necklace: Loop Knot Edition

On investigating how to make an adjustable-length sliding knot necklace, I have come across 4 different versions of knots to use. There may be more. As I become aware of them, I will add links here. However, here are the versions of which I am aware.

1. What I'm calling the easiest knot
2. What I'm calling the loop knot (this tutorial)
3. What is called the barrel knot
4. I'm still trying to find the fourth one, but that is more of a macrame knot

Below are the instructions for what I am calling the loop knot. I call it that because one makes a loop with which to create a knot.

For equipment, you will need:

1. A tape measure.
2. Something to cut with, like a pair of scissors.

For supplies, you will need:

1. A cord. I am using a 2mm leather cord. I have seen instructions for 1.5mm cords, 2mm satin cords, and leather lacing; so it is really up to you want you want to use. Just make sure it will allow the knots to slide (no chains, twine, etc.).

Measure the widest part of your head. This may be from the tip of your nose and around your ears, although it could be any part. You just need to make sure it is the widest part of YOUR head. I apparently need 25½" to get around my nose; the top of my head is only 22¾".

NOTE: This is the MINIMUM length you need for your necklace. By all means, make it longer if you wish. Pick any measurement ABOVE what you get in this step.

Add 8 inches to that measurement. These 8 inches are going to be used up by the sliding knots.

Measure the cord to the length you calculated and cut it at that point.

If your necklace is going to have a charm with a bail, run the cord through the bail. Otherwise, skip this step.

Place your cord down in a loop with overlapping ends, as seen in the picture. You may not need the tape to hold the cord down. My cord kept wanting to curl back up into the size of the spool. So, if you are using leather cord off of a spoon, you may want to have some painter's tape handy. We will begin by working on the bottom side of the loop.

Measure 4 inches from the end of the cord, and fold this over into a V shape.

Place the V on top of the main circle body and take hold of the spot of overlap. The loose end of your cord should now be above the other two strands of the cord.

Take the loose end of the cord and wrap it behind, under, and in front of the other two strands of the cord.

Wrap the loose cord end around a second time, making sure it is on the thumb side of the first loop.

Wrap the loose cord end behind the other two strands of the cord one last time.

Take the loose cord end and pass it through the loop your holding with your thumb. (I'll try and take a less fuzzy picture the next time I tie this knot.)

Pull on the loose cord end and the strand it is part of at the same time. This will tighten up the knot. Don't make it too tight, as you want it to be able to slide.

Flip over your entire loop. You should now have the other loose end below the loop body. Repeat steps 5 through 12 for this loose end. You now have an adjustable leather necklace. You could also do this for a bracelet; just measure the widest portion of your hand and wrist instead of your head and follow the same process.

If you didn't use a charm with a bail, you can attach any charm that has a hole in it. Simply run the cord through the hole, then pull the other end of the cord through the loop in the hole. You have just created a knot to hold your charm!

Here is why I looked into this. I now have a cord I can use as a watch chain, and I can adjust the length of the chain dependent upon how far the buttons are from the watch and how much droop I want. The pictures show the concept is valid. However, I need to figure out how to make the leather cord not curl like it's still on the spool. Figured it out!
