I received a free sample of Post It Super Stick Dry Erase Surface 6ft by 4 ft and I loved it.  I only wish I had this many moons ago.  The surface is big, but  can be cut to any size you want or need.  I have been using my surface to practice school work with my little guy.  It makes studying fun and it easy to work on a wall.  Makes it easy for my little guy to review what we did.  I really love this product. [This review was collected as part of a promotion.]
