I came across this after the meeting and it made me think of the issue of the kinds of materials we could provide people to build with other than furniture. Some of the group weren't happy with working with cardboard but thin wooden board like this with slats in could make some really interesting pieces and they're certainly easier to put together and handle, and are maybe more accessible for members of the public who aren't comfortable or familiar with working this way. The idea of things slotting together, there's already a template - vary the shapes, sizes - could this work?
