Mapping with a Caliper Ruler

Many years ago I learned how to use a caliper ruler to measure brows and find certain points of reference. After using this formula so many times I was actually able to memorize it - which if you use it enough you will too. The caliper ruler is a great way to start learning and exploring brow symmetry. By combining the use of a caliper ruler and pre-inked brow mapping string you will get the most precise brow measurements!
