I try to keep the same standard of responsible consumption for our art supplies as well. I try to use things that can eventually end up in the compost and return to the earth. I also like the girls to know and realize the connections of where things come from. Our crayons are made of bee's wax, the paint brushes are wooden, the paints we use are from minerals. We order them online or buy them at a Waldorf school but they know that before the store it came from the earth, a tree or an animal. The separation many children have from the origin of the things in their life are very common these days. Their things come 'from the store.' I believe that if people were more conscious of the link between where things came from and the production side of things they would be far more likely to care for our planet.
I like to have jars of goodies around for the girls to create from.
