Madeira's Glamour Thread is ideal for serging, embroidery, decorative sewing, even crocheting and knitting. This metalized serger thread is a combination of 65% viscose and 35% metalized polyester and has professional-grade tensile strength that gives you a smooth sewing experience. This thread features a consistently high quality throughout the whole spool and is more economically priced than lower-quality metallic threads. Each spool contains 110 yards. Madeira's more traditional spool shape eliminates the "drop off" and tangling problems associated with the elongated spools many other manufacturers use. And all Madeira spools come with double-locking end caps to keep the thread neat and tidy. We recommend using Madeira Glamour Needles when using this thread for smooth and consistent stitches. Fly fisherman Pat Dorsey recommends this thread for the wing of his Top Secret Midge.
