Mettler Silk thread is not wrapped in silk. It is 100% cotton with a "silk" finish. It is a 50/3 thread that is also very nice for hand applique. Bernina recommends it for their machines, and I have used it with my Bernina, but I use Gutterman (very linty) and Prescencia (very little lint) without any problems, too.
