Chances are all of us have done some coloring book stuff--either as kids or even adults. Adult coloring books are still enjoying good sales & some of those for kids have pix that are fun to color.
So my 'Q' is simple... Have you ever used stamping to add to coloring book pics?
Here's one I'm working on from an adult CB. I'm not ready to color it yet. And I may have access to a kid's CB so I can try that too.
Oops! I realize I should have shown the original drawing before I stamped it.
Oh well... Anyhoo I'm adding a view of it colored. Most of the color is colored pencils, but I used crayons over the pencils & burnished.
