InvisaFil

The "WOW" you can't see! InvisaFil is fabulous for all types of applique, especially English Paper Piecing and ribbon applique as your stitches will be virtually invisible!
A remarkable silk-like, cottonized polyester, this ultra-fine but surprisingly strong thread has cotton-like characteristics and negligible stretch while also feeling soft in the hand. InvisaFil makes for super low bulk stitches and virtually “disappears” into cotton or wool backgrounds.
