Beeswax will strengthen your thread and reduce knotting in hand sewing. Simply place the thread in the open notch and draw it back and forth several times to coat the thread. Beeswax has many varied uses. Try it for lubricating zippers and smoothing the surface of your iron. It is also useful for easy the tracks in sticky drawers and windows. The handy holder keeps the wax clean and serves as an excellent protective case.
