All thats needed, are a small pair of plyers with a cutting edge and round on the end, as shown in photo above, 4 inch piece of memory wire, 8-7mm beads and a charms of your choice. I chose a small leaf for mine,
Step 1. Cut a four inch piece of memory wire. Using your plyers, make a small round turn on one end of the wire. This keeps your beads from fall off.
Step 2. Place 4 beads on the wire, then place your charm. This will be the center of the ring as shown below.
Step 5. With your fingers manipulate the wire into a round circle and, wala... you now have a charm that eaisly slips onto the glass stem.
