Wax strengthens thread, smooths floss, and reduces tangles. Gently pull thread between thumb and waxer two times, then pull thread between thumb and finger to smooth. The color of beeswax is variable. Sunlight is a natural bleach for beeswax. If you would like to lighten the color of your waxer, place near a window for a few days. Waxer will not melt unless temperature is in excess of 140 degrees F.
