Fiber: The basic element, or raw materials, from either a natural or processed source, that is twisted or spun together to create a thread or yarn.
Over dyed: The process of applying additional color or colors over a previously dyed thread or yarn.
Ply: The elements that are twisted together to create a strand of thread. Embroidery floss is a six-strand thread that can be divided into six strands. Each strand has two plies that are not designed for separation.
Space dyed: The process of dying natural or bleached threads with one or more colors using a consistent or random pattern.
Stitching Length: The length of thread (usually 12″ to 18″) cut from the spool, card, reel or skein and then threaded into a needle. Softer, more fragile threads should be cut to the shorter end of the range to avoid wear from rubbing against the rough canvas threads.
Strand: A unit of thread that is generally indivisible. Pearl cotton and Impressions are examples of a single-strand thread.
Thread: The unit as it comes from the skein, spool or card. Threads are used to embellish fabric, canvas and other media. We categorize them by type: cotton, linen, metallic, rayon, silk, silk/wool, synthetic and wool.
