Arts and Crafts
Join the craft resurgence movement! Happily there is a huge range of gear available in natural materials, albeit, typically at the higher end of the market. For example, paint in metal tubes, wooden brushes with natural bristles, paper, canvas, sponges (go for natural sponges), charcoals, water colours, colouring pencils and crayons. Avoid markers, highlighters, foam shapes etc.
