Monofilament #40 Thread is a strong, clear nylon thread that blends in with the fabric being sewn. Monofilament thread sews well, meaning that it is easy to set upper thread tension and tension remains consistent. Thread feeds through the top of the transparent cover, which provides a silicone coating and keeps the thread clean and tangle free. No thread stand is necessary.
This #40 thread is equivalent to a commercial size V-40. We recommend sewing this thread with a #14 needle. This thread is used for fine leather goods, furniture and upholstery.
