Polyester monofilament invisible thread. Soft and heat resistant. Clear (matte-finish) Size = Very Very Fine - 2,200yds.
Our Monopoly is Polyester and therefore is dryer safe, won't yellow, won't go brittle over time, & can be ironed on a lower heat setting. We suggest using a Polyester Invisible Monofilament thread over a Nylon monofilament (which as a lower melting point) for these reasons.
