How would this work with a set of tarot cards?
there's some really neat dark themed tarot decks but i don't know if the cards are too "busy" for it to look good
I've done it with both normal and tarot cards. Tarot cards can look more busy and take more work to wreck but it is doable. When I did it I used more paint on the cards and played around with altering the images more.
If you just write on them with a sharpie like you can on the playing cards it can get a bit lost.
