What a fun project! You might like this idea-- My dh covered one wall in our family room with sheets of the stuff they put inside of bathtubs and showers. Not sure what it is called?? Anyway, it functions just like a dry erase board. We keep buckets of dry erase markers on hand and it is very convenient for teaching lessons, keeping track of projects and assignments, and there is also plenty of room left over for little hands to color and draw. We love our dry erase wall, it is great!
Or you could paint an area with chalkboard paint and have a chalkboard wall instead! We considered that as well, but opted for the dry erase wall instead. I was concerned about clouds of chalk dust floating around the house
