I was going to buy a hood for my tablet but watched a youtube vid of a guy useing a piece of cardboard, he explain why, and it makes sence the sides of a hood will inhibet your ability to use features and cardboard allows you to have easy access to the tablet. I am useing a MOD 8 1/4" pizza top box. ( MOD=made on demand) of course you have to be lucky enough to have a MOD pizzaria in your area, lol.  My 8" tablet fis perfect in between the flaps.

It is creative
