WonderFil, Specialty Threads, InvisaFil, 2-Ply Cottonized Soft Polyester, Silk-Like Thread for Fine Sewing, 100wt - Dark Grey, 400m

Our finest thread line, InvisaFil, is a remarkable 100wt, 2-ply polyester-cotton. This ultra-fine yet surprisingly strong thread has cotton-like characteristics and negligible stretch while feeling soft in the hand. InvisaFil has very low bulk 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 to show your seams. It's available in 60 subtle to brilliant colors with a matte finish, so you can choose how much you want to show the thread (or not at all).
