A little while ago, I was talking about starting up a community for coloring art. Remember? Well, I've done it.
Everyone, please join, watch, tell your friends about, shout from the highest rafters, and link to:
The Harry Potterverse Coloring Book
I've already got an introductory image up there. Clicking on it will take you to a site where you can download a hires PDF of it so you can color and upload as a comment!!!
Please read the bio page if you have any questions. ^_^
