For a unique and embellished look with a serger, use Madeira Glamour No. 8. Madeira Glamour No. 8 is a metalized serger thread with professional tensile strength. This thread runs smoothly through the looper and makes embellishing with a serger more fun than ever. Glamour's high quality is consistent through the whole spool and still costs less than lower quality metallic threads. With Glamour, even ordinary seams, hems and edges become extraordinary.
