Now that you've mastered the art of forehead tagging, it's time to take it to the next level. In this step, we'll be using a combination of advanced trigonometry and pure, unadulterated creativity to map the intricate topography of the human brow.
Start by dividing your subject's face into a grid of 12 equal sections, each one representing a different brow region.
Download the official Forehead Taggings Brow Grid Template and print it out on a large piece of cardboard or acetate.
Using a trusty ol' ol' marker, carefully draw a series of bold, black lines onto the grid, tracing the exact contours of the subject's brows.
Take a step back, admire your handiwork, and revel in the sheer complexity of the human brow.
