Maybe it's because of the baby on the way... but, I've had the idea to make a sketch book for kids that is more or less "guided". You could also call it an activity book, but it doesn't tell you how to do it, it just gets you started. Like drawing "games" you could play with two people where one person is telling the other what to draw, but not how to draw it. Anyway, I'm too late, because Taro Gomi has already done it. She has a few different books like this. And they all look like they'd be pretty fun to do (if I was a kid this is).
