My brother loved his psych ward crafts when he was in the day program. Of course he got to do copper foil rubbings. I'm not particular of cardboard as a base media or acrylic paint as a paint type (depending on quality, anyway.)   To have to paint with that would annoy me something awful.

Not being able to work properly with the materials given is the biggest annoyance in art for me.  Even bigger than having to work when I don't feel creative. Combining both is incredibly bad.
