Use 2 pairs of flat-nose pliers to open a jump ring, and connect a heart and 2-hole teardrop, making sure the shimmer sides of both crystals are facing the same direction. Securely close jump ring. For best way to open and close loops, see Jump Ring Hint in Jewelry Basics 101 (PDF)
Pop the hoop open, and add the drop. The folded part of the hoop should be at the front; the wider flat part of the hoop should be at the back of the ear.
Repeat for other earring, and enjoy!
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.
