Waxed Thread

Sometimes called waxed cord or waxed string, waxed thread is often found in craft stores or fabric stores. It is typically made by coating individual strands of thread in wax, often bee’s wax. This final thread is often three or four ply for greater strength and durability. Though there are many different uses for waxed cord, it is often preferred for applications that may be exposed to the elements, since the wax makes it fairly waterproof and less likely to mildew.

Waxed thread is often used in handmade crafts and sewing applications such as hand-sewn leather goods and making strings of beads and other jewelry. The wax on the thread provides lubrication that can make sewing easier, as the thread is able to pass through dense objects like leather more easily. It should not be used with a sewing machine, however, as the machine can quickly wear off the wax and be damaged by the buildup.

The wax applied to waxed cord can actually affect the color of the thread and make it appear darker. This means that in the long term the thread may seem to lighten, when really it is simply the wax wearing off. Users of waxed thread may want to consider choosing a thread that seems slightly too dark, since as the wax wears off it will become the proper color.
