Here is a very simple little lanyard, that lets you have a decent length of cord with you in a small package. The simple slip knot!
Slip the cord through the ring/bale etc (I'm using about 55-56 inches)
Loop over and snug down
Tie the first slip knot, try to keep the cords straight through the slip knots.
Repeat until you only have a few inches remaining
After the last knot, slip the ends through the loop, and snug it up.
Tie a simple overhand to finish it off, and you end up with a lanyard that shrinks 56" of paracord into a lanyard not much longer than a 111mm SAK.
Lastly, go through and straighten the knots out, and you are done!
Does this work for the badge?
