This hugely popular super fine thread is available in the full collection of 60 colors for all InvisaFil™ enthusiasts. Wonderfil finest thread line, InvisaFil™, is a remarkable silk-like 100wt, 2-ply 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”, making it the ultimate choice for English paper piecing, delicate lace designs, fine fabrics, creating texture when micro quilting, or whenever you don’t want your stitching to show. It is available in 60 subtle to bright colors with a matte finish, so you can choose how much want the thread to show (or not at all)!
