Aurifil 40wt Cotton

Aurifil 40wt is a popular all-round cotton thread suitable for both hand and machine quilting. It offers a balance of strength, smoothness, and stitch definition, making it well suited to quilting on domestic and longarm machines, general sewing, and visible topstitching on garments including dresses, skirts, shirts, and soft tailoring. The 40wt weight produces a slightly more defined, traditional stitch line compared to finer weights, and is available in large 1000m spools, 4700m cones, and variegated large spools.

Recommended needle: 80/12 Microtex/Sharp, Universal or Denim.

Aurifil thread is 100% long-staple Egyptian cotton, grown in the MAKO region of Egypt on the river Nile. Long-staple fibres produce a stronger, smoother thread with minimal lint. While not organic, Aurifil is Oeko-Tex Standard 100 certified - free from harmful chemicals and completely safe for human use, so you and your loved ones can wrap yourselves in those lovingly stitched quilts without worry. Aurifil is also BCI and FSC certified, and partners with Plastic Bank to offset ocean-bound plastic.
