That's a good idea! I have one question regarding using dry erase walls/sheets without the marker holder bar on the bottom...did you have the dry marker residue all over the floor all the time?
I just kept the erasers in a box on my desk, which was easy enough. We didn't have any problems with residue on the floors, either. It's just not a lot of residue, especially when you spread it out over such a huge surface.
