Here is another way to join the lanyard...a "fingercuff" adjustable sliding join.
The lanyard…. I started with 4 long strings. At the middle of the strings I did a bog standard 4-plait round braid, that I then joined into 8-plait. This made for a terminal loop. Then I split the braiding once again into long 4-plait braids. Instead of just joining these together though I “finger cuffed” these over the other thong to make a sliding join….this way the length of the thong can be adjusted AND a double loop of leather goes around the back of my neck to make this more comfortable.
Again a loop that would be braided to fit the compass, and a sliding adjustable length lanyard....this is my favored way of making neck lanyards now over the firesteel one above.
Simple 4-plait braid with only a short section of 8-plait to make that loop, and the fingercuffs are open 4-plait over the other side, terminated with a crown and wall knot.
I hope these help.
