Here are a few of my earring holders in my Antiques and More strife space. I crafted the gold ones out of picture frames and non-stick kitchen drawer liners. Strong yarn through the Mesh holds them in place in the back. I handcrafted these bottle top earrings recently and love the RECYCLE symbolizim.
The large metal bird holder seemed a bit sqwished so I just purchased these dancing lady earring holders. They can hold up to 3 pairs and are super cute. They are light weight though so if you are using them at an outdoor setting the wind could knock them over. Also Nothing too heavy. I am going to stabilize them in some way with charms and hot glue on the bottom. Best part is besides how gypsy they are is they come out to about a dollar each!
I found this vintage Jewelry box for displaying little charms. Here is a fun similar purple velvet treasure box on amazon. - They also have black or white but why not be royal! The clear top is great ;)
