Okay, first you measure your wrist with measuring tape.
Then, cut the tape according so, but add a little extra for both comfort and for the clasps. Repeat for all three strands, stick (some, not all!!) of it onto say a table or so.
Then you take one piece of tape, and begin rolling it up.
1) You turn the colored side down, sticky side up.
2) Take maybe half an inch of tape, fold it over itself. Repeat until you get one strand of tape. Repeat for all three pieces of tape.
You'll need a friend to hold this.
Braid all three strands like normal, be careful you don't horribly bend the strands. Take a piece of tape and tape the ends so they come undone.
Last, you take some sort of glue (super-glue, I'm not sure, nor am I sure about hot glue gun), I haven't tried this step. So I highly recommend you FIRST TRY THE GLUE ON A SMALL PIECE OF TAPE.
If it works, ether glue may work, glue the clasps to the ends of the bracelets and your done!!! :)
Or, you could duct tape the bracelet onto your wrist and keep it on always. Just take a piece of tape and take the ends of the bracelet (which should be on your wrist) and tape them together.
