How to Clean a Copic Mistake

Step One: Make a Mistake! Check. Done. See aforeposted (I know its not a word).

Step Two: Lightly use your Colorless Blender 0 to tap and swoosh towards you (technical jargon lol), by gently rubbing the tip of your copic sketch with the paper and lifting away from the paper. Repeat. Many times. Oh and as an aside, I seem to be getting better with the camera and this picture shows alot of the detail in the coloring, especially the Mouse's blush.

Step Three: Watch the color fade. Tap and Swoosh. Move on to the next part of your coloring. Return to your mistake. Tap and Swoosh.

Step Four (optional): If your mistake was like mine, dark and rather larger, you may want to turn your paper over and repeat the tapping and swooshing.

Step Five: Smile at your almost completely faded mistake!

Some extra tips: Remember, you are using a blender and it likes to disperse color. Be careful not to touch any of your colored image with the blender, as it will drain the color and give it a tye-dyed effect (fun technique, when intentional, maybe tomorrow's tutorial HINT HINT!).
Do not give up! I have found that 95% of my mistakes will come out, after much tapping and swooshing.
