How it works

Bottle cap painting ideas need paint that grips
Watery poster paint beads up on a smooth plastic cap. A paint marker holds better, and a sticker holds best. That is why most designs here use the cap in its own color and sort the caps instead of painting them.
Sort before you start
Murals take caps by the hundred, so sort them by color into tubs as they come in. The saved caps of soft drink, water and milk bottles differ in size as well as color, which the snowman print and the dotted wrapping paper rely on.
- Glue caps open side down. The rim gives the glue a ring to grip and the flat top faces out.
- A garland needs no holes: two caps glued rim to rim trap the string between them.
Questions and answers
What are bottle cap art ideas for kids?
The ones with no hole to punch: a ladybug with marker spots, a caterpillar of green caps glued in a wave, grapes printed with a cap top, a memory game with stickers hidden inside. Most mobiles and wind chimes need a hole in every cap.
What are some ideas to paint on bottle caps?
Small, bold marks: ladybug spots, an X or an O for tic-tac-toe, a letter of the alphabet, the dots of a die, a number for a counting caterpillar. A paint marker draws them in one pass on smooth plastic.
How do you make a mural out of bottle caps?
Draw the picture on a board, sort caps by color, lay them loose to check the fit, then glue each one open side down. Start with outlines and fill inward. The rainbow arch and the sunflower are the plainest to begin with.
What are plastic bottle caps made of?
Commonly polyethylene or polypropylene, and often a different plastic from the bottle they close. Watery paint beads up on a smooth cap, and stickers, tape and paint markers do better.
