King Tut is one of nature's finest threads. It is certified Egyptian grown, extra-long staple cotton and designed for quilting on both Home sewing machines and Longarm machines. King Tut thread is 3-ply 40wt thread made for quilting. With the finest spinning, twisting, dyeing and finishing techniques, King Tut has extremely low lint. You and your machine will thoroughly enjoy the quilting experience. It is available in both variegated and solid colors. As this is a thicker thread, we recommend using a larger needle such as 90/14.
