Hi and welcome! Feel free to wander over to the Introductions area & you'll get a very warm welcome.
I was unclear about this in the beginning, and thought perhaps you are too, hence my post. I initially thought that the skins were for protection. Actually, they are primarily for decoration. They do protect a little, from surface scratches, and maybe from dirt, a little, but not very much. Since they are 99% (imho) decorative, they don't need to cover the corners. They would actually be a pain in the patoot to put on if they covered corners.
Again, welcome
Kim
