Mine is (if you have hooded eyelids) to put a lighter shadow on the bit near your lashline and then a darker shadow in the crease to make your eyes pop. This goes against the grain of doing a smoky eye from your lash and buffing it out but I think it looks a lot better!

What's your best makeup trick or technique? Do you have anything you'd recommend? (just curious!)
