So far, this is the best method that I have found. It doesn't eliminate wrinkles entirely, but wrinkles are minimized. Clothes are easily organized this way, and it is very easy to find anything I need while travelling. The photo below shows pants, jeans, shirts, and pajamas folded and vertically stacked. A few more items will fit on top. When I get to my destination, I can easily pull out the items I need without disturbing all the others.
Here are links to Marie Kondo showing her folding method for Tops, camisoles, and socks; Odd-shaped clothing; and T-shirts (YouTube videos).
Another Yay! for tidying. :)
