I started with this pattern:

The pattern is for the older generation Kindle and that Kindle is a bit bigger than the newer one. So, I shrank the pattern size. And I was a bit confused at the exact steps that the pattern took to construct the keeper. I am horrible at patterns with no pictures. LOL! I decided to just put it together how I wanted to.
