On my way to chuck the cheap dollar store crayons we have right now--geez there's lead in everything, isn't there? I never liked them anyhow, they break really easily. I wanted to get dd a set of stockmar block crayons for Christmas, so I think I'm off to do that instead. I have to say that slightly before she turned 2, the crayon eating really dropped off and she almost never eats them now, thank goodness. Markers, however, are still used for writing on your face, hands and tongue. Ick :LOL .
I made a bunch of home made play dough for fun/safe arts and crafts--it's really easy (I think if you search the crafts forum you'll find links to recipes). DD loves it--I dig out all the weird kitchen utensils and cookie cutters and let her have fun with it. At least if she eats it I know what was in it--I just bought myself a set of all natural food colorings too, so I can put those in next time I make some.
