This is a great idea for any sort of DIY artwork: trace a simple graphic onto three canvases, and paint. So much more esthetically pleasing than if you were to just trace and paint onto one canvas. Plus i love the whale idea for a little boy room :)
In my closet at my parents house, I had sharpies and anyone that came in my room would sign the back wall of my closet! idea for guest room: Paint dresser all white and leave a sharpie for guests to "sign". kinda like my old duct tape idea.
