I have a specific talent for foretelling the future - I say it's specific because a generic deck of tarot cards won't really help me. I'm artsy and do a lot of DIY things, so I'd like to make my own deck. But I heard there's a ritual or enchantment you have to do while creating your own deck - and I haven't seen any blank cards for sale anywhere. Least none that I can draw on. Has anyone done this?
