Ever put on your favorite necklace to realize that its too long for the neckline you're wearing? This happens to me a lot with larger sweaters. No fear! You can repurpose an orphaned earring stud to help. Simply put on your necklace, gather the excess chain at the back and slip an old earring through the chain. Put the back on the earring and turn the necklace right way around. Voila! No more snagged or hidden necklaces!
