Cut the wire about 8mm from the top of the crystal.
Create a simple loop on the other end, so you now have a link.
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.
Assemble the earrings using the jump rings. Place two wrapped head pins onto a jump ring and attach it to the bottom of the crystal link. Then add another jump ring and two more wrapped head pins. You will add a total of 5 jump rings, and the last jump ring will only have one wrapped head pin.
