## Why It Works
Egg carton cups are a near-perfect form factor for small part organization: roughly the diameter of a finger, deep enough to hold items without spilling, and made from rigid material that holds its shape. The corrugated cardboard construction is lightweight and won't scratch drawer surfaces. Commercial organizer inserts do the same job at a markup; egg cartons do it free.
## How to Do It
1. Collect cardboard egg cartons (not foam — cardboard is sturdier and easier to cut cleanly).
2. For loose cup organizers: cut individual cups apart with scissors. Use them as-is or group them on a tray.
3. For custom drawer inserts: measure your drawer interior. Cut the carton into strips of the right width. Line the bottom of the drawer.
4. For a connected organizer: cut the lid off the carton, leaving the base with all 12 cups intact. Trim to fit the space.
5. To label: write directly on the cardboard with a marker, or cut small labels and glue them to the cup fronts.
## Pro Tips
- Stack two carton bottoms (cups interlocking) for travel or storage — the cups nest together and hold items in place without spilling.
- For workshop use: a full carton base works perfectly for sorting screws, nails, or hardware by size when working on a project.
- Paint or line the cups with decorative paper if you want these to look presentable in a visible space.
## When to Use This
Workshop and garage organization for screws, nails, and hardware. Jewelry organization for rings, earrings, and small pendants. Craft room organization for buttons, beads, and small findings. Kitchen junk drawer triage.
