Sharpie Markers, Crayola markers, and colored pencils
This was a little doodle I came up with one day while I was playing with my 15 month old son. As you can see, he "helped" me with some of it. I gave him a marker when he was about a year old, and ever since, he's been a junior artist. It seems I've created a coloring monster, and I couldn't be more proud!
