When you tie this bracelet to your wrist, make a wish. Now, as often as possible, run your fingers over the charm or bead and fill it with your energy while you think about your wish. Don't ever take this bracelet off, it will eventually fall off itself, and when it does all of the stored energy in it will pour out into the universe and come back to you in a positive way. If you need to undo your wish, simply untie the knot or cut the string and burn/bury the bracelet.
The colours of each bracelet come with their own associations, both positive and negative, though these bracelets are intended for positive use.
