Human skin is really only good for parchment and whatnot. It's too thin to be used for protection and it's lacking hair for warmth. Maybe you could turn her into some kind of drum? I'm not sure how much tension human leather can take.

Anyway, again we were talking about things that are or are not normal. Human artifacts have been created throughout history, but they're generally pretty rare. They're noteable. Shrunken heads, bone churches, skin books, a skin lamp shade. I think someone made some gloves once?

So, wearing my mum would not be normal. I'm gonna say you can't because all of your friends would disown you.
