Aurifil 50wt is slightly thicker than Aurifil 80wt thread and, although it's great for free motion quilting with it on home sewing machine… it's is absolutely perfect for  Machine Piecing.

That’s right – on top and in the bobbin this 2 ply thread makes piecing a joy. On top, the Aurifil 50wt/2ply helps seams press flat, flat, flat. Less need to worry about achieving that “scant ¼” seam allowance. In the bobbin you’ll be thrilled to load yards and yards of this 2ply thread, resulting in less bobbin changes (promise). 


  • Use a Microtex Sharp size 70/10 or larger for piecing with Aurifil 50wt.
  • With Aurifil 50wt in the bobbin there’s no need to adjust tension when piecing.  Choose a smaller stitch length to gain strength in numbers and have some fun!
