I need the extra thickness of a cover to hold a device like a Kindle. Not so much big hands, though I'm 6'2", as much as old hands with arthritis and carpel tunnel. When I was a child in my first year of public school we had to use those big fat pencils because our hands didn't work well with smaller, normal sized pencils. Now that I'm getting older I'm once again looking for fatter pens and pencils!
