Those who know me know that I'm very anti the Instagram brow... I appreciate the art of it (on a drag queen) but for real life it's a no no for me. I have really tailored the way I do my brow... and I like to call this technique "feathered brow"... for the fact that it helps the brows look soft and bushy.
I have this genius little art brush from Micheal's Art Supplies... it's the most narrow little angled brush that creates the most perfect hair like strokes.
When picking up the brow gel, I use the back of my hand as a palette and flip the brush back and forth... this keep the bristles tight and compacted together... I find that if you don't do this, the lines wont be as thin.
Then I start (with very gentle pressure) drawing on a few hair like stokes...
