IdeaPaint Home Clear ($140) is a transparent paint that can be used on top of any paint — regardless of the color — transforming the space into a whiteboard surface. Paint it on the walls, on the kids' table, or even on their doors, and watch it become a marker free-for-all as lil ones turn it into a creative doodling space. Any colored dry-erase markers will write on the surface (though IdeaPaint does make its own low-odor versions), and almost any cloth or clean sock can erase it — without the dust caused by chalk. Both low-VOC- and Greenguard Children and Schools-certified, the paint solution is safe for kids' bedrooms and playrooms. So what do you think? Would you replace the chalkboard for a whiteboard?
