I have lots of colors of this Mettler Silk Finish thread in my thread stash. I have used it for general sewing of clothing and for hand applique but never tried it for machine quilting before now. It is a 50 weight/3 ply thread that is 100% cotton. I would say it is a medium weight thread with very little lint left in the machine.Other facts – Bernina stitch regulator (BSR), size #12 topstitch needle, 2.0 stitch length, 4.5 tension. I did find that I should have adjusted the tension a bit tighter. The batting in this sample is Fairfield 80 cotton/20 polyester.
I have had good luck using this thread for hand applique and use it for piecing quilt blocks together and now can say I liked using it for machine quilting too. The backtracking does build up and look a little heavier but it wasn’t a problem stitching through the multiple layers of thread.
I will use this thread again for machine quilting when I want a medium thread.
