My friend had a idea  about using a binder clip instead of tape for friendship bracelets!
This way you aren't wasting tape and it won't slip!  Just clip it on something 
THE SPRIAL
I made mine green for st. Patrick's Day!! 
You need two long different colored strings, fold in half, and tie.
 Take the two different colored strands and tape them down.  
Make a 4 with one of the outside strands 
Take the other one and put it through the hole.  Pull tight 
Keep on doing it.
It should look like this
Keep on going and you are done!
