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. 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! Pack B002 contains Bleached White 104, Blue Grey 179, Chestnut 401, Peach 410, Tan 464, and Khaki 507
