Sometimes Maia and I hang out at the kitchen table and draw dot-to-dots for each other. I don't remember how this started exactly, but we've been doing it every once in a while for a couple of years now. She makes them for me to trace and I make them for her to trace. The one above is Maia's. When she was younger she would would just make random dots all over the page for me to connect up. Now she lines them up to form a more coherent shape or design.
Here's a super simple one I made for Maia. I generally keep mine fairly abstract although I've been known to do a unicorn on request.

This one started out as a dot-to-dot and turned into a maze, which I think is pretty cool. (We also draw straight-up mazes for each other sometimes.)
Fun times at our table with simple paper and markers!
