Aurifil thread is known among quilters as the best cotton thread you can find due to its versatility, strength, lustrous colour, and the fact that it produces virtually no lint.
This is the heaviest weight thread that Aurifil offers 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. When using 12wt in a machine, it is recommended that a much thinner thread be used in the bobbin, like the 40wt.
With thread produced in Italy, Aurifil leads the industry in good stewardship. They have a partnership with Plastic Bank, a social enterprise headquartered in Canada which aims to clean up plastic waste from our oceans while providing valuable opportunities for people living in poverty. Aurifil thread is Oeko-Tex certified, meaning that the thread is certified free of harmful chemicals.
