Use the golden ratio tool to measure a perfectly symmetrical pair of brows. Points that have to be marked on both brows: 1,2,3,4,5,6. Keep in mind the basic rules (beginning the thickest, pt 3 height between the heights of 1 and 4, lower line rising up until 6. ONE PAIR IS ENOUGH (◑‿◐). NB! PLEASE TAKE THE PICTURE FROM DIRECTLY ABOVE YOUR DRAWING (otherwise even symmetrical outlines will not look symmetrical in the picture)!
