I think it would be cool if we had hole punched card sleeves to put on a keyring. Then our spellbooks would be MUCH more modular. You could just take "pages" out of your spellbook and stick them on another keyring to make another spellbook. Unfortunately the closest thing to hole punched card sleeves that would actually work for this that I know of are ID card protectors which are way too expensive to buy in bulk.
I mean maybe I could hole punch the corners of a card sleeve, stick a string through them, then hope a card still fits in the sleeve? I'm not sure how doable this would be, and if I get it wrong I might ruins some sleeves.
Does anybody have any advice on how I can do this if at all?
Thanks!
