I had a really nice cover for my NST when new but I liked the feeling of the reader without it. I eventually settled on this value minded solution and have been much happier since. My wife does make fun of it as do some other people as well but i think it provides as much or more protection than the high priced specialty products. Bonus: it fits my new Glow Light also.
Well I tried adding photos but it did not work so I will describe it. I used a padded mailing envelope that I had laying around (the kind with a liner of bubble wrap). It was too wide so I cut the envelope down to size and used packing tape to close the cut side back together. After resizing I just stuck some Velcro (which I also had on hand) to the front and back at the top of the now to be Nook sleeve. Then all that was needed to be done was make a Velcro strap to keep it closed, which all this involved was cutting a around a two inch piece of said Velcro of the opposite mating material. Now my Nook sleeve may not be the prettiest thing but it has character (and that is all that really counts). The envelope that I used had some miles on it, so it has remnants of a couple of shipping labels. Now it has some stains and more packing tape to repair the damage one of my dogs had done when he chewed on it. It may not be the most beautiful creation but it does serve the purpose.
