Those colorful, sturdy plastic caps from liquid laundry detergent bottles are surprisingly versatile—and far too useful to throw away. Made from durable HDPE or PP plastic, they’re water-resistant, easy to clean, and perfect for DIY organization, crafts, and household hacks.

Here are 10 practical, eco-friendly ways to give them a second life:
🌿 1. Seed Starters for Your Garden
Poke a few drainage holes in the bottom.
Fill with potting soil and plant seeds.
Place on a sunny windowsill—transplant when sprouted!
🎨 2. Paint Palettes for Kids or Artists
The curved shape holds small amounts of paint perfectly.
Great for watercolors, acrylics, or finger paints.
Rinse and reuse again and again.
🧴 3. Travel-Sized Toiletry ContainersClean thoroughly, then fill with shampoo, conditioner, or lotion for trips.
Secure with a small piece of tape or a rubber band (they don’t seal tightly, so use for short trips only).
🔧 4. Hardware & Small Parts Organizer
Keep screws, nails, beads, buttons, or fishing hooks sorted in your workshop or craft room.
Label with a marker or place in a drawer tray.
🧊 5. Ice Cube Trays for Broth or Coffee
Pour leftover coffee, bone broth, or herb-infused water into caps.
Freeze, then pop out cubes for cooking or iced drinks.
🧵 6. Pincushions or Needle Holders
Fill with scrap fabric or cotton balls, then stick sewing needles or pins upright.
Keeps sharp objects safe and visible.
🧼 7. Soap Savers or Loofah Holders
Place a sliver of bar soap inside to extend its life.
The ridged base helps create lather—perfect for the shower!
🎄 8. Holiday Ornaments or Gift Tags
Paint, glitter, or decoupage caps for festive tree decorations.
Punch a hole, add twine, and write names for rustic gift tags.
