Aurifil is a premier Italian thread company favored by quilters, sewists, and textile artists worldwide. It is renowned for manufacturing exceptionally smooth, strong threads crafted from 100% Egyptian Mako cotton. Aurifil threads are highly regarded for several distinct qualities: Premium Material: They use extra-long staple Egyptian cotton, which creates a stronger, smoother thread that is less likely to break or fray. Virtually Lint-Free: The thread is mercerized, a process that swells the fibers to make them stronger and removes fuzz so that your sewing machine stays cleaner. Vibrant Colors: They are known for a massive, vibrant color palette that resists fading and bleeding.
