Tips:

  • When hand sewing, use short thread (12-18 inches) to avoid thread breakage and tangling.

50wt - orange polish

Aurifil's 50wt sewing thread is the most versatile and most popular of Aurifil's cotton threads. It is strong but thin and produces a remarkably flat and sharp seam.

  • 4.0 long arm machine needle (50wt on lower bobbin)

40wt - Green bobbin

  • lower and upper bobbin thread
  • machine application
  • machine embroidery

Tips:

  • When using 12wt sewing thread on a sewing machine, we recommend a much thinner thread for the lower half, for example 40wt.
  • When using 12wt sewing thread on a long arm machine, go slow and use a longer stitch and silicone insert if needed.
