I bought a craft cart from Target that has 7 drawers. The drawers pullout and has a lid to open (helps from losing stuff. I’m also using as a nightstand at the head of my bed.

I labeled the drawers by type of supplies.
1. Findings
2. stringing material
3. pendants
4. connectors and charms
5. Pearls, gemstones, and crystals
6. glass
7. other (like wood, etc)

Here’s some pix on how it looks in action:

I use ziplock bags to sort within the drawers.
also use little bags and labels the beads etc come with to sort them.

That’s how I sort my supplies.
Share how you sort your supplies (any kind). I could also use more organization tips!
