This tutorial will show you how to make a wrist lanyard using paracord and the cobra weave. This can be used to secure a key chain, knife, mutitool, camera, or cell phone, etc. I give all credit to Stormdrane for the cobra weave. He was the first person to make an instructables using the cobra.
You will need about 5 feet of paracord. I buy my 7-strand paracord on eBay and sometimes from the Supply Captain. I like keeping the iner strands in my paracord, but you can take them out if you so desire. Scissors, tape measure, lighter, and a key chain hook.
