Yes, little one, you can use those markers on the wall

Dying to write on the walls?  Idea Paint is your solution.  It turns any surface into a dry erase surface.  You know... those white boards that you can color on with special markers and it just wipes right off?  Think of blackboard paint... but it's white and there's no chalk.  Available online at IdeaPaint.com and at some Lowe's stores.
