Wow! There are some really nice covers here!
I just made something simple because my kindle cover was just intended to protect my Kindle from scratches in my purse. It's just 2 pieces of fabric with some batting in the center. Add the velcro. Then fold and sew for a pocket. It took longer to pick the cute cow fabric than to make it.
