The decorative element of the ball-end simple loop matches the style of the ear wire.
Make a simple loop on the ball-end of the head pin. Open slightly and add charm, making sure the front of the charm and ball face the same direction.
Add watermelon chevron bead, spacer and crystal and finish with a wrapped loop.
Use crimping pliers to round the wrapped loops so they aren't scratchy. The concave shape helps pull the wire in close to the wrap without chipping the bead underneath.
One or more parts (or tools) used in this project are no longer available, so we've moved the whole project into the "Misc Jewelry Tutorials with Issues" area while we decide what we want to do about it: find a good sub, re-make this project, or retire the tutorial.
