Kindle Fire CoverHere is what I used: upholstery fabric (khaki and red material) for the outside and fleece (gray material) for the interior liner. I wanted something durable for the outside and something soft that was not going to scratch the screen on the inside.
I cut the upholstery fabric first; 20" long and 6" wide (it probably wouldn't hurt to add 1/2" to both the length and the width) and laid it right side down on top of the fleece.
Stitch both of the long edges together on each side.
Here's wishing you the time to get creative and make something instead of running out to buy it.
