Step 1: Stuff You'll Need
1) A 4 feet of paracord
2) A Keyring and a snap hook (the snap hook is optional)
3)Any accessory like a bead, designed button, etc.
Step 2: Getting ready to start tying the knot
Find the middle of the cord. Hold on to it. Take the desired length of the keychain and mark it with the keyring, IF you want to attach it on this end. If you want to attach it on the other side, then mark the length with a twist tie or rubber band. If you are using a snap hook, you can use it instead of the twist tie to mark the length.
