I received the 3M- Post-it Super Sticky Dry Erase Surface and placed it in a small space in our craft room.  It is perfect for jotting down notes and brainstorming ideas for my next craft project.  I could see this being used in a classroom or kitchen or home office as well since it's sticking ability is fantastic and it is so easy to clean-up.   I use it on a smooth wall.  I just don't think it would work well on a textured wall...all the bumps would show through.
