I have made a lot of paracord bracelets in the past few months and I have found connecting the buckle to be troublesome and in the end I have burns and, because of the curved buckles I was using, you could never wear both sides of the bracelet (I always use two colors). Using this technique there is no buckle or knots, you can use both sides of the bracelet and its as easy to put on as slipping it over your hand!
Step 1: Materials
2 three foot lengths of paracord in the colors of your choice
Elastic Hair Ties (preferably a color that will blend in)
Step 2: Tie the first knots
Now because the hair tie is already a complete circle a really small portion of it with show on one side of your bracelet. However, it will be right next to the melted section at the end so when you turn the bracelet so that that section is on the palm side of your wrist it will also hide this. If you used a similar color to your bracelet you shouldn't be able to tell anyway.
