I made this a few years ago so I don’t have a step by step, but it’s VERY EASY! All you need is an empty frame, screen and hot glue. I used an old frame I had, just took out the glass. You can do the same, or find one at a thrift store, or online. The screen I picked up at Lowes, but you can get that a lot of places too. I did paint my frame brown to go with my bathroom, but you should do yours however you want :-).
I just cut the screen to fit the frame and hot glued it in place. It’s held fine for 3 years now, but if you are worried about it, you can use a staple gun too. I used the little prongs on the frame to help it out. Then I took all of my dangle earrings and put them on using the clear backs to hold them in place.
You will need to take it down, or lift it up to take the earring on and off, but it hold them well and looks nice too. Have fun making your own!
