Also I'm finding it difficult to differentiate stunts from aspects.
The easiest way I found to explain it to my friends was to take the example in FATE Accelerated and following the formula:
"Because I am [insert relevant Aspect], when I do [insert Approach for FATE acc, or specific action] to achieve [create an aspect, or other narrow action], I have a +2."
So for one PC who was a Faerie creature,Prince of the Cats, he had the following stunt:
Because I am [Prince of the Cats], I get a +2 to [Identify aspect] when I am calling the Neighborhood Council of Cats to gather information.
Stunts are free (do not cost Fate point) whereas calling an Aspect DOES cost a Fate point.
There are also stunts that you can only use once per gaming session.
In this case, one character had a Cloack of Thousand Faces and it worked that way:
Because I own [the Cloack of the Thousand Faces], once per game, I can change my [Role]. (In this game, "Role" was defined as what the Faerie character was pretending to be when he was amongst human, it was an temporary aspect that he could call to be more believable and competent when he was playing his human role).
