Sew Sassy is a 12 wt. 3-ply spun polyester thread designed for quilting, topstitching, decorative stitching and wool applique. Sew Sassy is designed for both machine stitching and hand stitching applications. With a selection of 40 beautiful colours including bright, neutral, matte, and bold colour options, you'll find the right colour tone for your project. Due to a tighter twist, Sew Sassy is smoother, stronger and less fuzzy than other 12 wt. polyester threads.
