cut some Paracord 2-3 feet long and melt the ends with a lighter.
Step 2: Making an Incomplete Square Knot
Make an incomplete square knot as shown.
Step 3: Making the Loop Smaller...
Make the loop of the-incomplete-square knot smaller. Make the ends' length as equal as possible.
Step 4: Push It In.
Push the ends through the loop.
Step 5: Two Knots
Make a knot (overhand knot) on the ends as shown.
Step 6: Time to Wear!
Wear it. Pull the ends to tighten. To secure, insert the ends as shown. So simple, right?
