I don’t wear a lot of jewelry, partly due to the fact that I periodically lose anything and everything smaller than the average kitchen appliance. I made this organizational device in an attempt to save at least some of my possessions from entropy, as well as to use some empty space on my long bathroom wall.
I’d seen some pictures of things like it floating around the intertubes, and hadn’t done any productive crafting for awhile, so I decided to wing it when I found an appropriately long and empty frame at the secondhand store. Apart from the frame, I used white paint (2-3 coats acrylic; it dried extremely fast), tacks, string, pins, and sticks. The sticks were from my parents’ backyard, and had been dried out for a few months in a shed (this is probably a good idea to get rid of bugs and to make sure the wood doesn’t shrink/warp post-use, although it wouldn’t matter too much for this project).
I cut the sticks to length and wrapped the ends with string, then used a tack to attach the string to the frame. There are probably better ways to do this (e.g. a staple gun), but I had tacks.

I left some nubs of stick to act as hangers, and also stuck in some straight pins (I arranged everything on the floor first to figure out how many hangers I needed). If you have heavier jewelry you might need small finish nails or something stronger, but if the pins are put in about half a centimetre and at an angle I find they’ll hold up most things.

The frame I bought already had a loop of wire at the top, and my wall already had a drywall screw in it, so hanging it up was pretty easy. You’d probably be okay with just a couple nails in the wall, but if your jewelry + frame = more than a few pounds, a drywall screw is probably a good idea.

Voila!
