Guest post: Aurifil’s essential guide to quilting threads

Aurifil threads

As part of our week-long series of free quilting tutorials for our World Craft Week, the lovely folk at Aurifil are sharing this guest post. Today they’re tackling an item that’s essential to every quilting project – thread! What are the different thread weights available and how do they affect your finished sewing? Over to them…

Here at Aurifil we’re thread makers… thread lovers… thread addicts, really. We simply can’t get enough of it! We could talk about thread all day and all night. Does that make us dull? We certainly hope not! With 270 cotton colors and 7 different cotton thread weights, our thread range has a little something for everyone – from simple straight line quilting, to detailed illustrative quilting, to hand quilting, and so much more.

One of the most common questions that we get is which of our threads is best for quilting, and the answer is they are all created for quilting. Here’s our guide to our seven different thread weights, plus our versatile monofilament thread, and what they offer…

Aurifil thread guide

50WT

The perfect choice for both piecing and quilting, the 50wt is our most popular thread, favored by both beginner and expert quilters.

  •  100% Cotton, 2 ply
  • Small Spool, Large Spool, Cone
  • Best needle choice: use a 80/12 Microtex/Sharp, Universal, Quilting, or Denim Needle OR a 4.0 Longarm Needle. Use 50wt in the bobbin too.

Our 50wt thread is truly our workhorse.It is the go-to for a large percentage of our designers, offering crisp flat seams for precision piecing. For quilting, it offers subtle definition and is the free motion quilter’s perfect companion.

Aurifil Designers Wendy Sheppard of Ivory Spring and Christa Watson of Christa Quilts both use 50wt as their go-to quilting thread. We just love the detail that they are able to achieve with their spectacular free motion quilting skills!

40WT

Aurifil 40wt thread has all the benefits of our 50wt, but with even greater definition. It is strong enough to withstand fast, dense stitching, and thin enough to support intricate detail.

  •  100% Cotton, 2 ply
  • Small Spool, Large Spool, Cone
  • Best needle choice: use a 80/12 Microtex/Sharp, Universal, or Denim Needle OR 90/14 or 75/11 Quilting Needle (use 40wt or 50wt in the bobbin) OR 3.5 or 4.0 Longarm Quilting Needle (use 50wt in the bobbin)

Barbara Persing of Fourth & Sixth Designs uses 40wt as her absolute go-to, for both piecing and quilting. One of her latest creations, Firelight Pink Peony, just took home a prize at the AQS show in Lancaster, PA!

28WT

Our 28wt thread is an amazing option for when you want your machine quilting to really shine. The weight of the thread allows for increased stitch definition so that the thread itself is as much a part of the finish look of the quilt as the fabric.

  •  100% Cotton, 2 ply
  • Small Spool, Large Spool, Cone
  • Best needle choice: use 90/14 Topstitch, Quilting, or Denim Needle (use 40wt or 50wt in the bobbin) OR 4.0 Longarm Needle (use 40wt or 50wt in the bobbin)

Quilter Maria Shell prefers to use Aurifil 28wt in her bobbin to create a secondary stitched design to that on the front. She likens it to looking at a photo negative… “The backsides of my quilts are not the reverse of color, but rather the absence of the piecework.”

12WT

Our 12wt thread, while perfectly lovely for use in a machine, is typically the go-to for hand-quilting. Strong, with enough heft to make a striking visual impact, it is both easy to use and produces fantastic results.

  •  100% Cotton, 2 ply
  • Small Spool, Large Spool, Cone
  • Use it with this needle: 100/16 or 90/14 Topstitch Needle (use 40wt in the bobbin) OR 4.5 Longarm Needle (use 28wt in the bobbin)

 Aurifil Designers Sarah Fielke and Anna Maria Horner both use our 12wt for all of their hand quilting.

FORTY3

Our Forty3 threads are the new kids on the block. Introduced in Houston last Fall (2017), they have all the versatility and lustrous color of the original 40 weight threads, with the added benefit of extra strength.

  • 100% Cotton, 3 ply
  • Cone
  • 90/14 Topstitch Needle (use 50wt in the bobbin) or 4.5 Longarm Needle (use 40wt 2ply or 50wt in the bobbin)

Karen Miller of RedBird Quilt Co. said of the Forty3 thread, “It doesn’t shred or break regardless of what direction I’m stitching in.  Many threads, (and longarms) like to go one direction or another and often have trouble going the “wrong” direction.  This thread worked without issue in all directions. I love that – I could stitch away and not have to plan out my direction.”

80WT

Our 80wt thread is delicate and a wonderful choice when it comes to applique, but it is also a fantastic option for detailed & delicate machine quilting!

  • 100% Cotton, 2 ply
  • Small Wooden Spool
  • Needles to use it with: use 70/10 or 80/12 Microtex/Sharp or Embroidery Needle (use 50wt in the bobbin)

Carolina Assmusen used 10 different shades of Aurifil 80wt thread to create this stunning mini quilt she has named “Spring Snow, New England”. The thinness of the thread has allowed her to fill in a large amount of thread painted details without distracting from the overall piece.

Aurifloss

At first glance one would assume that our floss is purely for embroidery or cross stitch, but it is also a great choice for hand quilting. Aurifloss is a 6-strand separating embroidery thread that allows you the ability to choose exactly how thick you would like your hand quilting to be.

  • 100% Cotton, 6-strand
  • Small Wooden Spool
  • Match needle according to project (Embroidery, Cross Stitch, Tatting, etc.)

Aurifil Designer Sharon Holland used Aurifloss from her Color Story thread collection to hand quilt this beautiful quilt.

Monofilament

Our monofilament thread is a fantastic option if you are quilting a highly colorful quilt yet do not want to make several thread changes throughout the quilting process.

  • 100% Nylon
  • Large Spool, Cone
  • Use it with:  80/12 or 70/10 Topstitching or Microtex/Sharp Needle OR 3.0 or 4.0 Longarm Needle (use 40wt, 50wt, or hand-wound monofilament in the bobbin)

Aurifil Designer Felice Regina of I Am Luna Sol uses it often in her quilting. One example is her Tula Nova quilt. She was able to create a custom quilting design without worrying about the thread overpowering the piecing and fabrics.
