All of our threads are all created with quilters in mind, but they also have special qualities that make them a firm favourite for different tasks that quilt-makers need.

Aurifil threads are loved for their quality, strength and lustrous finish, not to mention for their kindness to your sewing machine (they're created to produce less lint to clog things up).
