I loved doing this in art class. Art With Mr. E: Line Design w/Shading - Grade Very cool, fun art shading project from Art With Mr. E. he's an elementary art specialist. Try this with your kids (but I think grown ups would enjoy this too).
one of thes might just be the inspiration to my next tattoo. will have two at the same time after I give birth, one will be on my nape, and one to (an owl) to cover the old tattoo I have on my lower back :) owl drawing
