Instructions
Use the polymer clay to mold into different charms such as different Horcruxes or Hogwarts items, making sure to add a loop at the top for stringing it onto the bracelet.
Bake the charms according to the package directions.
Allow to cool.
Measure the wire around your wrist, then use the jewelry pliers to cut it a little bigger than the finished bracelet needs to be.
Use the pliers to make a loop at one end of the cut wire.
String the seed beads and charms in the desired order.
Make another loop at the other end of the wire with the pliers, leaving a little opening for hooking the first loop.
