Aurifil’s 100% Cotton 12wt thread is the heaviest weight thread that we offer and is perfect for hand applique, hand embroidery, hand quilting, cross stitch, embellishment, handmade lace, machine applique, blanket stitch, machine embroidery (especially for designs that use a longer stitch length), machine art quilting, Sashiko, redwork, lower looper serging, and longarm quilting.

Tips:

• When using 12wt thread by machine, we recommend using a much thinner thread in the bobbin, like our 40wt.
