Had to play around with it
At first I did a large black strip of liner and applied this lash - I really disliked the effect. I’ve also never been good with liquid liners so it just looked messy. I realized though that very little liner is needed so I experimented a bit and just dotted liner as imperceptibly as possible between my lashes (which are already quite dark). I trimmed the lash to about 3/4 and think it looks pretty good. Still need to play around with it a bit, but if at first you don’t like it - just try this method and maybe it will work better for you! (I like a much more natural look)
