I bought a shoe box sized gift box (so it’s pretty), and she keeps them in there. It’s not super organised, but they’re all in one place and she can find what she wants pretty easily.

U can buy a head band organizer from ali express or ebay it is similar like bangle stand

I keep all my daughter’s hair accessories, including head bands, in an old ice cream container.

You could get creative and perhaps make your own headband holder. Some great easy videos out there to watch on it. just google. Or you could arrange your headbands by colour inside a basket/recycled tin.

It depends what “material” they are made from and the shape of them. Not having seen them at all it is hard to make constructive suggestions

I pop them all in a big tub

Search pinterest for some ideas. Ive seen some great ones on there.
