I was looking at the BOM for card trick and it's the way I've mostly always seen and done which is 4 triangles for each color. See link below if you don't know what a card trick is.

In Anita Grossman Solomon's book that I have, she does a cardtrick using 3 squares for each color. Makes a lot of sense to me since squares are easier to work with and for me turn out much more exact.
My question - if it's done with squares, is that still a card trick? Or does it become a faux card trick?
