I looked at all the number cards in the upside-down position where they will be when the card is finished. I really wanted number 9 but it looked like a 6 and I didn't want to make cards that were 666 so I chose 8 which is the same right side up or upside-down. Some of the other numbers looked like letters and the face cards all inverted letters.
I also considered the suits that all look upside-down in the bottom corner except for the diamond.
My best guess was that it didn't matter.
