Box with crayons. My in-laws got us the pottery barn chair and the box was used for coloring in for a long time then it became a slide on our stairs. Sensory table with things that are ok to eat like oatmeal. And just add in measuring cups and utensils like spoons and spatulas. Play doh. If you are thinking things like painting I suggest putting some in a ziplock so it’s not messy. I’ve just started doing “crafts” with my 3 yo. Before then it’s providing materials to manipulate.
