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)!

Our ultra-fine 100wt InvisaFil thread is now available in mini-sized spools! Each InvisaFil Mini Pack contains a selection of six 400m spools with 10 color sets available for you to choose from. These Mini Packs are the perfect choice for anyone who needs a variety of colors without the need to purchase larger spools, or a great way for those who want to sample InvisaFil for the first time! Five InvisaFil Mini Pack color sets contain color selections inspired by Vikki Pignatelli, teacher and quilter enthusiast.
