Really nice cover! and nice daughter too! Can I borrow her?
Someone mentioned a charger. How about a small messenger bag? There's several tutes on line just google messenger bag instructions and you should get several. It should be easy to cut down on. I made a messenger bag for a laptop which would be too big for what you want. I made the strap long enough that my son can easily slip it over his head and carry it. Also lined it in dragon fabric which he loves.
