Sergers Mastering Your BERNINA® Thread Wearable art embellishment has necessitated the creation and marketing of many new thread types, such as rayons and metallics. Threads made in West Germany are left twist threads; Mettler and Isacord threads are also left twist. To test the twist of a thread: while holding the spool in the left hand, roll the strand of thread towards you with one thumb. Left twist will tighten, right twist will loosen. Notes Fiber - refers to the type of material used to produce the thread. Some commonly used threads: • Polyester Overlock Thread - such as Mettler Metrocor Thinner than regular sewing thread, eliminating bulk in serger stitch formations. An excellent all-purpose serger thread. • Texturized Nylon Thread - such as YLI Woolly Nylon and Mettler Metroflock. A very elastic thread with excellent coverage; perfect for rolled edges and knit seams. Available in solid and variegated colors, and metallics. • Polyester Topstitching Thread - such as YLI Jeans Stitch & Mettler Cordonnet - this heavy thread is used for decorative stitching, such as flatlocked seams and overcast edges. Also nice for cover and chain stitching. Available in solid and variegated colors. • Rayon Decorative Threads - such as YLI Pearl Crown Rayon & YLI Designer 6 - shiny threads for decorative applications. Pearl Crown Rayon is twisted, while Designer 6 is untwisted. Available in solid and variegated colors. • Metallic Decorative Threads - such as YLI Candlelight - adds a bit of glitz to seams and edgings. • Decorative Sewing Threads - sewing machine threads can also be used in the serger, and are particularly effective when several are used together as one thread. Storage of Thread Thread does wear out and should be stored with care to keep it usable as long as possible. Extreme moisture may cause thread to swell while very dry conditions can leave it dry and brittle as it ages. Store thread in a covered container (thread box with a lid, cabinet with doors, or drawers that close) if possible to keep it dust-free. Be wary of old spools of thread recovered from Grandma's sewing box. The fibers may be so weak and brittle that even if it sews into a seam, it may be so unstable that the garment or project will not hold together and the life of the project may be considerably shortened.
