5. Fairy Light Plastic Cup Lanterns
One of the most magical uses of plastic cups is turning them into glowing lantern ornaments.
Pierce small holes or cut decorative shapes into the cups, then place battery-operated fairy lights inside. Frosted or translucent cups diffuse the light softly, creating a warm glow.
These lanterns can be hung on trees, used for outdoor patios, or placed along shelves for cozy ambiance. They look especially beautiful in evening Pinterest photos.
