Invisible 100wt polyester monofilament thread. Designed for invisible applique and quilting.

MonoPoly is an invisible monofilament thread made from polyester, not nylon,. Because it is made from polyester filament, it is heat resistant and iron and dryer safe. Unlike nylon monofilament threads, MonoPoly won't become brittle over time or discolour. It is strong especially considering its fine diameter, has low stretch and is soft and pliable.

Each cone is wound with 10,000 yds.
