Just a simple Cobra stitch or Solomon bar wrapped around a hairband. The weave itself is naturally expandable. When tied tight around a piece of Paracord, it's tight like a knot. But tied around a hairband, it opens and closes with the stretching of the hairband!
Step 1: You Will Need:
1- Elastic only Hairband. No metal clasps, they will rub on your wrist. I use an older stretched out hairband. It fits better on my large wrist. A brand new hairband would be way too tight.
2- Approximately 6' of paracord
Step 2: Start Tying the Solomon Bar.
Start by tying a regular overhand knot. Then another, in the other direction. Then alternate back and forth creating the pattern.
Step 3: Continue Tying All the Way Aound Until You Reach Where You Started.
Step 4: Thread the 2 Loose Ends Through 2 of the Outer Loops From Where You Started .
Step 5: Trim, Melt and Flare the Ends So It Wont Pull Through. That's It!
The 2 color Tan & black bracelet pictured above was made the same way. I just melted two 3' pieces of paracord together. One black, one tan. Then put the hairband right on the joint, and start tying.
