It's 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. Needle Recommendations:
100/16 or 90/14 Topstitch Needle (40wt or 50wt in the bobbin)
4.5 Longarm Needle (28wt in the bobbin)
When using 12wt thread by machine, it's recommend using a much thinner thread in the bobbin, like 40wt or 50wt.
When using in a Longarm machine, quilt slowly, using a longer stitch and silicone conditioner where necessary.
