Thread > Sulky Polylite (60wt) Our 60 Wt. PolyLite thread creates delicate decorative stitches and crisp readable lettering. It looks and feels like silk but it is stronger and less expensive. You will love it for micro-stippling, piecing and fine detail quilting. It is ideal in the bobbin for any decorative project where you want to match the bobbin thread to the top thread because the underside will be visible. Quilters love new Sulky PolyLite because it flows like butter through a long-arm or domestic sewing machine with virtually no tension adjustments needed. The perfect companion bobbin thread for Sulky Metallics, Rayons and Invisible Threads.
