Get a wire hanger and hang wherever you'd like to store your necklaces. I put mine on the back of my closet door cuz I have a hanger holder thing there:)
Take a paper clip. It can be any size but I like to match up the paper clip with the size of the chain.
Adjust the one point so it's pointing outward
You now can slide the necklace there to hang:)
Now stick the paper clip onto the wire!
Voila! An easy and DIY organizer for your long necklaces:)
