Barrel knot

Usually the barrel knot is made at the end of a rope or cord for decorative purposes.

1. Make a little loop at the end of your cord. 
2. With the shorter end, wrap the cord multiple times around itself (two cords inside) back towards the loop. 
3. Wrap at least twice, but you can choose to make your barrel knots longer too, up to even 10 times.
4. At the end of the wrapping, push the cord end through the little loop you created in step 1.
5. Pull the longer end of the cord to tighten your barrel knot
6. Cut the short cord end close to the barrel knot.
