For the record, I had never done such a conversion before. Still, I told her that I would do what I could. I love a challenge, after all.
These are the earrings:
I decided that, instead of trying to pry off the backs, I would utilize the clips themselves. With a half hour, some beading wire, and a pair of French hooks, this is what I came up with:
How did I do it? Here is the back:
This is what the back shows: I wrapped the wire through the hole on the clip, and then anchored it by wrapping it once around the top rhinestone. Then, I simply did standard wire-wrapping to make the loop for the earwires, finishing it off by wrapping it around itself.
I am very pleased with the final product, especially since nothing I did harmed the original earring. Everything is reversible, so if my mother-in-law decides that the earwires don't work for her, I can revert them to their original form.
One last look...
Aren't they just lovely?
