12 Creative Ways to Reuse Tuna Cans
1. DIY candle holder (homemade candle)
One of the easiest upgrades is turning a tuna can into a candle.
Melt leftover candle wax, place a wick in the cleaned can, and pour in the melted wax. Once it sets, you’ll have a brand-new candle. Customize the outside with paint, twine, rope, or fabric.
2. Mini herb planters
Tuna cans are ideal for small indoor plants and herbs.
Punch a small drainage hole in the bottom, add soil, and plant herbs like basil, mint, or rosemary. They look great on a kitchen counter or windowsill.
3. Spice or tea organizers
If your kitchen cabinet feels cluttered, use tuna cans as quick storage.
They’re perfect for holding tea bags, seasoning packets, or small portions of spices.
4. Drawer dividers for small items
Keep small accessories separated and easy to find.
Use cans to sort items like rubber bands, bobby pins, paper clips, hair ties, or small craft pieces inside drawers.
5. Baking molds for mini cakes or tarts
With both ends removed, the can can work as a circular baking mold.
Add batter or crust and bake. This is great for mini cheesecakes, tartlets, or individual-sized desserts.
6. Wall-mounted organizers
Create vertical storage by attaching multiple cans to a wooden board and hanging it on the wall.
Use them to hold makeup brushes, pens, scissors, markers, or craft tools.
7. Emergency camping stove (wax fire starter)
Many campers use this simple trick.
Pack cardboard strips into the can and cover them with melted wax. Once lit, it works as a small improvised stove or fire starter.
8. Simple bird feeder
This is a fun outdoor reuse project.
Tie string to the sides, fill the can with birdseed, and hang it from a tree branch.
9. Small jewelry holder
Line the inside with felt or soft fabric.
It becomes a compact container for rings, earrings, hairpins, or other small accessories.
10. Natural drawer deodorizer with essential oils
Make an easy, fresh-smelling deodorizer for closets and drawers.
Add baking soda to the can and drip in a few drops of your favorite essential oil. This helps absorb odors and keeps spaces smelling clean.
11. Holiday and seasonal crafts
With paint and a bit of imagination, tuna cans can become:
- Christmas ornaments or mini décor containers
- Halloween lanterns
- Easter treat holders
12. Desk organizer for office supplies
On a desk, tuna cans work beautifully as:
- Pen and pencil holders
- Paper clip containers
- Catch-alls for small items
