BEST Eyeliner Tip Ever!

I read on Pinterest, of course, a tip for eyeliner that stays put. Use an old tiny eyeliner brush that you have washed (I ran mine through the dishwasher) and brush it over your mascara brush. I tried this yesterday and it stays put all day with no smudging and no wearing off. Additionally, you can get a really good tightline (also known as invisible lining).  I have tried liquids, pencils, and gels and each has a downside. This seems to be the trick for me.
