100% Cotton. 325 metres / 356 yards per spool. Aurifil’s 100% Egyptian Cotton 12wt thread comes wound on a red spool. Aurifil threads produce virtually no lint and they are one of the most popular threads amongst the quilting community. The 12wt is the heaviest weight thread that Aurifil offer and is perfect for hand applique, hand embroidery, hand quilting, cross stitch, embellishment, handmade lace, machine applique, blanket stitch, buttonhole stitch, machine embroidery (especially for designs that use a longer stitch length), machine art quilting, Sashiko, redwork, lower looper serging, and longarm quilting. Needle Recommendations: 100/16 or 90/14 Topstitch Needle (50wt in the bobbin). Tips: When using 12wt thread by machine, we recommend using a much thinner thread in the bobbin, like our 50wt.
