I've got some ideas swirling around, but they are dependent on folks being able to write on a card and have that writing stay on the card permanently.
Say I wanted just a normal playing card to be written on with a sharpie. Assuming giving the ink time to dry, would this stand up to shuffling?
If not, any other ideas. What could I a) make the card out of and b) write on the card with to make this happen?
I'm not wanting this for a prototype, but as a deck of cards that are sold to people who then write on them. So it will be out of my hands after production of the cards themselves.
