I have used it for tying quilts, for applique, for art quilts to add texture and as embellishment, for lettering quilt labels, and for sashiko-style pieces (true sashiko thread has no lustre). I have also used it for embroidery and cross stitch, thinking about trying it for needlepoint and hardranger. It comes in five sizes (weights). No, Elizabeth, I would not put it in my sewing machine.
