Add a 3mm bicone, 4mm rondelle, 18mm emerald cut rectangle, and a final 4mm rondelle bead to a head pin.
Use a 1-step looper to trim and make a loop all in one step.
Or, for detailed instructions to make head pin loops, and safest best way to open and close loops, see: Jewelry Basics 101 (PDF).
Use chain nose pliers to finish closing loop (if necessary), and twist slightly sideways to add beaded dangle to ear wire.
Repeat. Make sure all loops are securely closed.
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.
