i did this a few years ago (without having seen the video) but with a mesh screen, like the type used on a porch door, and it has lasted for years! I also added a small pocket at the bottom of my screen by folding the material over to catch any fallen earrings.
Cute, but this would only work for these type of earrings, not post earrings. It looks really nice though and is a great idea and accent for your bathroom. :)
1) ripping apart underwear / sweaters
2) making it into something provocative
3) you modeling your creation at the end (damn!)
Great idea though, and the clothes hanger is perfect as you can move it to just about anywhere you need to! Nice.
