Canterbury 20" x 30" Black Wall Mount Magnetic This Chalkboard Sign with Eraser (Hanging Wall Chalkboard) is perfect for writing daily affirmations or even having your kids write them. This chalkboard is  also big enough to hang on a wall in your bedroom etc. It comes in a nice little frame and ready to hang. It gives you plenty of room to write and doodle as well. I am pretty happy with this products and so are kids. Hours of endless entertainment can be found here~
