Hi Marlene, firstly I’m so sorry for the delayed reply. For some reason your comment was attached to another link and I only just discovered it.
With the line and curl trick, the eyelash curler plays a big role in getting good results. As I highlighted in my post too, Kevyn Aucoin and Shu Uemura curlers tend to sit better against the lash line. You can also apply a thicker line of eyeliner to the curler to begin with – just to judge how much closer you should be placing the curler on your lash line. I hope these pointers will help get the perfect placement of liner for you. My apologies about the delayed reply again.
