My school has access to Netter's online atlas. The online atlas lets us download plates for free with our choice of label and lines, lines only, and no labels no lines. I grab the lines-no labels images, copy them to Word, change the color to B&W, lighten them, and then color the photocopies with prismacolor pencils. I like this better than a coloring book. I also draw muscles around just bones this way. Netter has an isolated spine AP and lat view I use a lot. Just a thought.
