Cardboard was one of the few things you could not eat on the Ekotown festival in the Amsterdam forest park. We made birds and elephants with the audience! It’s always nice to see adults and children working together. Sometimes people think we do children’s workshops (parents like to see us as a kindergarten). The idea that playing and tinkering and crafting together is childish is still strong with some people. But especially when they work together, adults and children inspire each other in the best way. Children learn from the skill, structure and endurance of the parents, parents learn to loosen up, be serviceable, explain and mainly: play.
