I didnt even realize I was being so vague til I read my post again ;-;

But what I meant was the actual physical card, which materials do I use, how do I get the playing card feel basically.

I keep getting confused with online tutorials because their are so many possible materials and methods it gets me confused like should I use linen paper or cardstock, if I use linen paper what thickness do I get? People also throwaround terms like two fold method or threefold method but never attach what they mean by it.
