Sacredly necessary art.
To me, the art area was a living thing. The shelves there were not stocked with things to be had, but materials to be interacted with. My kindergarteners always had paint, even if I had to buy it myself, which was often the case. The classroom didn’t have an easel (which horrified me), and so, if memory serves, I built my own. Details are fuzzy, but somehow cup hooks were involved.
