We decided the only thing our Kobo Mini needed was a case to keep its screen from getting scratched. So, this morning, first thing, we set about making him a case. We used 2 rectangles of Dollar Store felt, and in less than a morning, we had this:
We made cut-outs for the top where you turn it on and for the bottom where you insert the cord to sync it to the laptop. We used one of our own polymer buttons and a bright hair elastic. It is perfect.
