MonoPoly by Superior Threads
100 wt. monofilament polyester thread. Designed for invisible applique and quilting.
This reduced-sheen monofilament polyester is the best choice when it comes to invisible threads. Unlike other monofilament threads made from nylon, Monopoly is 100% polyester. Commonly referred to as an invisible thread due to its fineness and reduced-sheen, Monopoly is great for the bobbin or top. Available in two colors, Smoke (for dark fabrics) and Clear (for light fabrics).
