Well, lately I have been. I found a novel medium: watercolor crayons.
The kids and I have been experimenting with them for a few days now. I actually would not recommend these for kids, because you do have to be pretty precise with the actual "painting" part. Otherwise everything turns brown. Here are a few of the quickies I did to pass our summer seclusion this week so far. ( I apologize in advance for the really dim lighting. That was the brightest natural light I could find. Our windows are ''special" with extra tint on the outside.)
Not bad for only a couple of hours each. This last one also has been outlined and drawn with charcoal. I was going for a modern looking stained glass effect. Could be awful cute in some girls rooms don't you think?
**Update** The water color crayons are Faber-Castell and they are good for older kids. My 5 and 7 year old with a little practice have been able to make some paintings without the browning effect.
