Aurifil Thread

While Aurifil 50wt thread is the most popular, the weight you choose depends on the type of quilting you are doing, the stage of quilting you are in and the effects you wish to achieve. Larger numbers translate into finer thread. Here are some basics at a glance, but you can read our Aurifil Thread Weight Comparison for more information.

• 80wt - Adds superfine detail and makes stitches that settle into the piece.
• 50wt - Creates a beautiful subtle effect to allow the piecing to shine.

• 28wt - Offers beautiful texture with hand stitching and directs attention to the decorative stitching when used for machine quilting.
• 12wt - Produces bold designs for big stitch hand-quilting and bobbin work.
