Handy in every room!

I think one of these could be handy in every room!  I have one that I bought that hangs inside our back door and I love it.  I love how it can collect little mementos and they don't need to be pinned or taped or stapeled etc, things can just slide into the little pockets.  I imagine different sizes and kinds of frames.  I can see 8x10 standing frames in a teenager's room with movie ticket stubs and notes and pictures from friends. Or a poster size one with deep pockets in my little gals room with all her masterpiece drawings in it.  I can see one inside a laundry room cupboard with clothes washing instructions, tags or found bills.  Or in a kitchen cupboard with recipe notes, measurment equivelents or substitutions scratched out and stuck in there.  

Where could you use one?
