I went on a hunt last night for a quilted Kindle Cover. There are many sites that promise the ultimate sewing experience, but either they guide you off to something to buy or they want to sell you a pattern.
Then I found www.chicaandjo.com/2009/09/03/make-a-custom-kindle-cover-case. The instructions and pictures make it very clear how to make your own cover and it is free.
I plan on making at least two for family. So if anyone was thinking about doing this as a new project I think you'll like this site.
