Hey!I just use the smoulder eye kohl and run it along the inside of the upper lid,over and back until I'm happy with it.You could also try pulling the eyelid upward so you can get a better look at what you're doing.I'm not really sure if there's any real technique for doing it but I hope that helps!Works for me!
Agree..a softer pencil like Smolder does the trick beautifully...but it tends to smear. I've also done this with Graphblack Technakhol with less smearing.
I use Graphblack technakohl line my waterline then shut my eye for 5 seconds and bam, I've tightlined. It's a tricky procedure to actually go all the way to tightline, but lining ur waterline and shutting ur eyes is the easiest way
