Aurifil is 100% Egyptian Cotton, grown in the MAKO region of Egypt on the river Nile. When considering the quality of cotton we can make the comparison to that of wine, different geographic areas offer different attributes to the raw material. Aurifil thread is long staple, which refers to the length of the fibers in the raw cotton Boll, the length of the fibers determine the quality of the cotton.

The Aurifil production process is based in Milan, Italy. It’s here where the thread undergoes 15 steps before it becomes a spool ready for use.

We are proud to offer our 100% Egyptian Cotton thread in 12wt, 28wt, 40wt, 50wt, 80wt, 40wt/3ply and a 6-strand floss. Our Wool thread is available in 12wt and we also produce a Nylon Monofilament.

We know that finding that perfect color is key for your projects, so we’re happy to offer our threads in a wide variety of colours, including a strong sampling of variegated threads.

While Aurifil threads are not organic, we are proud to be Oeko-Tex certified. Oeko-Tex certification relates to how a product is processed, including things like dyes and finishes used. It means that our threads are certified free of harmful chemicals and are completely safe for human use. Or… in quilter’s terms, you and your loved ones can wrap yourselves in those lovingly stitched quilts without worry!

Our thread weight is determined by something called Number English or Ne. Ne is a measure of linear density and refers to the number of hanks (840yd or 770m) of skein material that weigh 1lb. For instance, 50 hanks (42,000yd or 38,500m) or our 50wt thread (Ne 50) weighs 1lb. Under this system, the higher the number, the finer the thread.

Aurifil thread is not waxed, but it is passed through a transparent paraffin oil during the winding process. It is this treatment that eventually helps the thread to glide through your machine. It does not leave any type of residue, simply serving to increase functionality to ensure the highest level of ease for the end user.

Yes! Aurifil thread is mercerized which is a process that not only strengthens the thread, but also provides it with a beautiful sheen.

As with any colorful textiles, Aurifil threads may bleed if not cared for properly. We have taken care to classify each of our colors as Indanthren or Reactive and have outlined proper care for both on all thread product pages. Following these standards of care ensures that your Aurifil colors will not bleed and will look rich and vibrant for years to come!

Indanthren colors are our ‘work-horse’ colors. They are seen as more heavy-duty and have a high level of colorfastness. Reactive colors are a bit less stable. They are created with a reactive dye, meaning that the color reacts to and bonds with the fiber during the dyeing process. They are less commonly used with our threads as they are can be more prone to bleed, requiring a different type of care. 23 of our 270 available Cotton colors are reactive.

The * indicates a reactive colour.

We do not produce silk threads, but for a similar look, we would recommend checking out our new 100% Cotton 80wt thread. It is thin, strong, and produces a stunningly beautiful result!

Our 50wt thread is thinner than the 40wt, making it ideal for piecing. It is this thinness that provides flatter, more accurate seams resulting in a truly professional finished product. When it comes to quilting, the 50wt is a fantastic choice because it sinks into the fabrics, creating the perfect amount of definition without being overbearing, allowing the piecing to be the star of the show!

The best wt for quilting truly depends on the type of quilting you are looking to achieve: 80wt allows for superfine detail; 50wt offers a beautiful subtle effect to allow the piecing to shine; 40wt provides greater stitch definition while still highlighting the piecing; 28wt by machine allows your stitching to shine with bold results and by hand creates beautiful texture; 12wt is our go-to for big stitch hand quilting.

Our 50wt thread is the ideal weight for piecing because it results in flat, non-bulky seams. It is a fine, strong thread that virtually disappears.

As a family company we’re committed to working with independent Brick & Mortar quilt shops. We’ve made a commitment to our stockists that Aurifil won’t be sold to Large chain retailers and never sold by Aurifil to the final consumer. We work hard and invest heavily in supporting Quilt Shops, including Alex Veronelli’s infamous traveling lecture series! We donate heavily every year to charities and community projects. We’re proud to be a generous organisation that gives back to our beautiful and creative community.

Because our 80wt is such a delicate, thin thread, we recommend using a very thin, very sharp needle when machine sewing. It also helps to take your time and sew slowly. For hand sewing, some users like to use a thread conditioner, though we find that it’s not necessary. We suggest using lengths no longer than 14”-16″ for best results and minimal breakage. Don’t pull too hard, but don’t be afraid to be firm with your stitches. Our favorite hand sewing needle for this weight is the Tulip Hiroshima needle #10.
