Wonderfil Invisafil Thread

Wonderfil InvisaFil - 100wt Cottonized Polyester Thread

Our 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)!

Material: 2-ply Cottonized Polyester
Weight: 100wt
Sizes: 400m (437yd), 2500m (2734yd), 9144m (10000yd)
Usages: Stitch in the ditch, top and bottom thread, bottom thread for delicate machine embroidery, hand and machine appliqué, free motion quilting, stippling, English paper piecing.
