Good advice for women and men. Tess Panzer:
Invest In Locking Ear Backs – Keep your earrings on your ears with earring backs that lock into place. Generally, the backs that come with your earrings are designed to keep them in place, but do not, however, offer any real security mechanisms beyond that.
I use Chrysmela, which is more precisely engineered.
Pin Your Earrings In Place – You could, for example have a cork on your night stand and pin your pairs to it when you take them off to go to bed.
Another use for wine bottle corks.
Hook Earrings To Each Other – When you take off your earrings, attach them to each other by poking one stud through the backing of the other and securing it with the second backing. This way, your earrings will never be apart and if you lose one, you lose both. After all, what’s one without the other.
Maybe jewelry manufacturers will take a clue and sell earrings in threes rather than twos.
