#2 Reuse and Recycle
Save tiny plastic bags to keep your necklaces from tangling - drape the clasp out and seal the bag with a small section of the chain on the outside.
Day-of-the-week pill containers are great for keeping things organized with perfectly sized spots for studs and rings.
A small piece of cardboard is a great way to travel with multiple stud earrings, just poke them through and put the backs on the other side, gently wrap in one of your shirts or blouses. Just don't forget which one!
