Frequently Asked Questions

Is Aurifil worth the price?

Yes — for quilters who value cotton thread, Aurifil is worth every penny. The fiber quality, color accuracy, and consistency are exceptional. The 50wt is particularly valued for precision piecing because it produces flatter, more accurate seams than heavier threads.

How do Aurifil colors compare to Kona Cotton?

Aurifil and Kona do not use the same color naming system — there’s no direct cross-reference. Many quilters use Aurifil’s printed color cards to find the closest match to their fabrics. The 270+ color range means most fabric colors have a close thread match.

Does Aurifil work on a longarm?

Yes — Aurifil 50wt works well on most longarm machines in the large spool format. It produces more cotton lint than polyester threads, so clean your machine more frequently when using it. It’s particularly popular for custom show quilt work.
