Invisible / Transparent - either nylon or polyester
• Strong but nylon thread is not heat resistant (a hot iron could melt it)
• Can become brittle from laundering and exposure over time
• Comes in clear and smoke colorations
• Typically used when you don’t want the thread to be noticeable
• Can be a little difficult to work with
Metallic - used for decorative stitching or embroidery
• Can be used for hand or machine sewing
• Breaks easily.
• Try using Sewer’s Aid when sewing with metallic thread
Elastic - thread with fine elastic within it.
• Used for smocking or shirring
• Thread should match the fabric in most cases. If you can’t find an exact match, select a color one or two shades darker.
• Darker shades blend in more and lighter shades stand out more
• When sewing a stretchy fabric such as a knit or spandex fabric, use polyester thread as it has some give to it.
• Do not use hand-sewing thread in the machine; it is for hand-sewing only.
• In most cases, the same thread should also be used in the bobbin. For machine embroidery, there is special bobbin thread that comes in black and white. When using top stitching thread, all-purpose thread is often used in the bobbin. But when sewing heavy duty items (canvas and upholstery) the heavier thread should be used for both the needle and the bobbin.
