Credit to P.S I love you
1. Cut 2 pieces of rope, whatever your size your wrists are. (you could also make it into a necklace)
2. Knot it.
3. Repeat as many knots as you want.
4. Take your chosen duct tape and cut a strip (however thick you want) and tape it around the section you'd like.
5. In the picture they have knotted it togethor, I suggest you get a clip (you can buy them from most craft shops) Depending on which one you get will depend on what you do now, but it's so simple, I don't think I need to tell you how to attatch the clip, if you get stuck just search your clip name and how to attatch it :)
