Lint-free never felt so good. Designed with award-winning quilter Libby Lehman, Bottom Line Thread 631 Deep Purple makes a fantastic bobbin thread for any type of sewing. It's lightweight, blendable colors are so easily matched with any top thread. Invisible applique and binding is a breeze with Bottom Line as it glides through layers of fabric without any extra friction like other polyester threads can. It's also fantastic for micro stippling due to the fine nature of the thread. Ideal for hand and machine applique, detail quilting, micro stippling, stitch-in-the-ditch, bobbin thread, trapunto, binding, free standing lace, heirloom sewing, and fine garment construction.
