I ended up cleaning out my RL jewellery box this afternoon. What a mess! To get some sort of order to my earrings, I cut up some pieces of plastic mesh and used them to hold the earrings.
As I trimmed the mesh, adjoining pieces had the little bits of mesh left sticking out. I trimmed those off and they make wonderful little ice cubes!
If you don't have plastic mesh and need ice cubes, another option is the packages of expanding crystals that are used in floral displays. You can quite often find these at dollar stores.
