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 :)
Simple wall hanging for baby's nursery--also makes a great baby shower gift! Easy to make, inexpensive family of safety pins. I would find one with five frames, the last one with the two large safety pins surrounded by little safety pins of varying sizes.
