I'm now selling a Kindle case on etsy
I first came across etsy - a site for selling handmade or vintage stuff - when I came across a series of pictures of boyfriends wearing hand made hats their girlfriends had made (and not looking to pleased about having a hand-knitted hat on their head).
Then when I got a Kindle I went looking there to see what sort of cases were available. I was pleasantly surprised to see loads of good stuff.
When I got my Kindle I made a cardboard case for it. At Christmas I got a proper case and since then I've been meaning to offer my cardboard case for sale on etsy, purely for my own amusement. If I sell one, I'll make another. If it really takes off, I might we quite busy fulfilling orders. Unlikely.
Feel free to prove me wrong.
