So i've been dabbling with eyeliners lately.. being useing MAC fluidline in blacktrack religiously and recently found revlons colorstay eyeliner in black.. but I always wondering if it was possible to use eyeshadow (preferably Urban Decary - Perversion shadow) as eyeliner? Wondering if it has good or even better staying power than the other eyeliners? Eyeshadow just has a easier application process (for me) and it would save me a lot of time when putting on my makeup. I also use UDPP under all my eye makeup as well. 
Thank you~
