if I'm doing a dark paint like art jam, I put it in the shape I want depending on how dramatic I am going, usually out a little and up into the crease. If i'm doing light eyes and using like soft ochre or painterly, then I put it all over, even where I do my highlight.......it depends what you are doing with it I guess, I use UDPP under it too, some people don't do that but man UDPP and paint pots = all day eyes!!
