InvisaFil™ is a remarkable silk-like 100wt, 2-ply cottonized polyester with a matte finish. This ultra-fine but surprisingly strong thread has cotton-like characteristics and negligible stretch while also feeling soft in the hand.

InvisaFil™ makes very fine stitches that virtually disappear, making it the ultimate choice for English paper piecing, hand and machine appliqué, delicate lace designs, fine fabrics, creating texture when micro quilting, or whenever you don’t want your stitching to show.
