Step 1: Materials
simple/decorative frame (i used a long frame with detailed framing)
cardboard matching the size of your frame (from any box lying around)
plastic mesh sheet (can be found in the knitting section; if you go to a craft store you can choose from many colors; i choose a lighter color to contrast my darker earrings; depending on the size of your frame, you may need more than one sheet)
hammer and nails (to hang the frame)
Step 2: Remove the Backing
Step 3: Measure and Cut the Plastic Mesh
Step 4: Measure and Cut Cardboard
Measure and cut the cardboard so it looks like a frame too. About 1cm is good. This cardboard frame may show through the mesh, but you can paint it a nice color or leave as is. It won't make much of a difference.
Step 5: Secure the Plastic Mesh and Cardboard to the Frame
You can use glue to glue down the mesh sheet or use a flat tack to tack the mesh down. It will depend on the type of frame you have.
Because of the depth of my frame, I was able to put the original back piece and create a space that allowed my earrings to hang.
Step 6: Hang Up Your Art Piece and Display Your Earrings
Step 7: Be Creative
Step 8: Questions
Sorry for the lack of pictures. I didn't intend on posting it.
For a simpler route, buy a metal mesh letter tray (at any office supply shop or walmart), tie a ribbon and hang that up. That's what I used before I put more thought into it.
