So I created "Make Your Own Color-by-Number Blank Clip Art". Its crazy easy to use the blanks:
1. Choose a Color-by-Number blank. The clips are 8"x8", just the right size to drop into a vertical or horizontal document without any adjusting and come in black lines with white or transparent fill.
2. Choose a color key or make your own. I made 2 variations of color keys: A) for 8 count crayon boxes and B) for 12 count crayon boxes and 16 count colored pencil sets.
3. Drop your chosen Color-by-Number blank into your favorite document creation program. Then use text boxes to layer your code right on top of the color-by-number blank. You can also make a color key page by creating new document with the same text boxes and switch out the blank for the full color key.
4. Add color! Obviously this is the step my kids love the most.
