^ The pencils
^ Pencils turned into purest CYAN in photoshop by going Image>Mode>Duotone and then clicking the black square and making it 30% cyan and 0% everything else.
^ And then you print the Cyan onto some Bristol board or whatever and ink it and then the pencil lines barely show up and you have two copies of your drawing. you can also use this method to turn a little doodle into a big inkable piece. Oh boy!
