Users can't create flairs, they can only select them (if the sub permits it) from a list created by mods.
You can ask an active mod in the sub you'd like to have a specific flair to add it in the list.
I've noticed a few folks, like Professor_de_la_pas seem to use them often and effectively. I'll keep an eye out for the subs that allow them to use those flairs.
FYI Flairs are sub specific.
Yes, understood that from earlier. It appears quicker to find those subs allowing the cool flairs by scanning the /All page for posts with cool flairs and noting in which subs they are allowed ... for future reference.
