Quick Tip: How to fake eyeliner when you run out

I ran out of my eyeliner a couple days ago and I hate when that happens and i'm not able to run to the store to get some. I did go last week and walmart was sold out of eyeliner! That makes me mad. Well anyways a trick i came up with to "fake" having eyeliner on to add definition to your eyes by taking a small shadow brush (I use one from sonia kashuk) and placing black eyeshadow on the brush (I use the black from the Maybelline Stylish Smokes Charcoal Quad) and applying it on the bottom lash line. I tried it today and it seemed to stay on the entire school day without using any primer either. Its a good trick to use if you want a similar look of eyeliner if you don't have any on hand. Let me know your thoughts on this and if it helps. The products I used are shown below.
