Quick project in challenge format #1/12
Garden stools. They fold into each other, have a slightly rough surface for anti-slip. They are made of recycled plastic, by injection molding. This means they are cheap to produce and easy to move. So that the stools are not blown away by the wind, filled with water or sand (or whatever you have)
, you can safely leave them in the garden under the sun or in the rain, and bright colors will not let you get lost.
