DIY Rose of Coffee Filter: Also use markers and spray bottle of water for kids to make. Have kids lightly color 3 coffee filters the round ones, and spray lightly with H2O, let dry. use pipe cleaners to secure a stem or use clothes line clip for butterflies.
Just lay a coffee filter in the bottom of the pot covering the hole before filling the pot. The soil will stay in the pot and the water will still drain out because that is what coffee filters are designed to do; let water through.
