Hemingworth Thread is known for their beautiful colors, impressive strength and their unique, patent pending spool cases. The durable spool cases extend the life of the thread by protecting it from dust, scratches, tangles, and the oils on our hands. In fact, the case is specially designed to prevent repeated contact with your hands. Simply remove the gel stopper and feed the thread through your machine. No need for spool caps and you can feed the thread from virtually any angle or position. Replace the stopper and store when finished.
