WonderFil - Invisafil Solid 100wt Polyester Thread - Medium Grey

Discover the "invisible" secret to perfect patchwork with InvisaFil™. This remarkable 100wt, 2-ply cottonized polyester thread offers a silk-like feel and a matte finish that allows your stitches to virtually disappear into your fabric. It is the premier choice for makers who want the strength of polyester with the soft, subtle characteristics of cotton.

InvisaFil™ is designed for high-precision tasks where low bulk is essential. It is a favorite for English Paper Piecing (EPP), hand and machine appliqué, and micro-quilting. Because it is so fine, it is also the perfect "Stitch in the Ditch" thread, hiding perfectly in the seams of your quilt top. Whether you are working on delicate lace or heavy-duty quilting texture, this thread provides the strength you need without the visibility you don't.
