I find that jewelry displays/ holders are quite expensive so I always start by trying to make something with what I ahev on hand.
That is what is so nice about this project: You will just need a small box, scissors and some stockings/ tights.
As you can see, my box was white so in the back you can see the light colour through the tights, but nobody is gonna see the back. Anyway, you can avoid this with a dark box or larger tights.
For costing next to nothing I think it's really practical. I hope you try it!
