Lay your tear drop shaped earrings down on some newspaper or cardboard. Mine were not flat, which would have been optimal, but they worked fine anyway.
Spray them with an even coat of spray adhesive on one side
I bought this really nice hexagon shaped glitter that sparkled like crazy. You can use any kind you'd like and in any color
Sprinkle the earrings with the glitter, covering them well on one side
Turn them over and do the same on the flip side
Make sure they're covered completely. Then shake them off and reapply glitter if necessary for full coverage
When dried, stick your jump ring through the hole
And then string your french hook onto the jump ring. Close the opening and move it into the earring hole
You're holiday party ready now!
