Finding decent clip art is probably the biggest hurdle -- most of what's out on the web is very low-res and will print "yucky."

My best tip is to find coloring books, scan them in hi-res and then color them in a graphics program. I have a whole slew of coloring books for this purpose and a wicked laaaaarge collection of scanned, colored and cleaned up images that I use for all of my graphics.

If you find yourself stuck for finding a specific character, let me know and I'll check to see if I have anything I can link you to.
