Challenge 6 is draw a childhood toy. This is a fox puppet that my grandmother had. We kids loved it but were always a little wary of it because it's teeth were fake but sharp, and its eyes make it look fierce. Now it's mine, and I believe it made the same kind of impression on my own kids.
Challenge 7: draw a jar from the kitchen.
Challenge 17: draw a musical instrument. This is no problem in my house, as we have several. I tried to capture the shadows. I should also try to capture the color sometime. It's a beautiful cello.
