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, hand and machine appliqué, 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 colours with a matte finish, so you can choose how much want the thread to show (or not at all)!

Miles ★★★★★

The 100wt weight is a game-changer for invisible mending—it glides through my machine without any of the tangling I get with thicker threads. The nude shade blends seamlessly into light fabrics, and the 2500m spool means I won't be reordering for a while.

Aurora L. ★★★★★

Finally, a thread that actually disappears into the fabric—this nude color blends perfectly with my medium-toned cotton pieces. The 100wt polyester is so fine I barely have to rethread my needle, yet it holds up through multiple seams without breaking. Sewing delicate hems now feels effortless.

Andrew I. ★★★★★

This thread is so fine it disappears into the fabric, yet I’ve had zero breakage even on dense seams. The 2500m spool lasts forever and the nude shade blends perfectly with my light cottons. Truly a game-changer for invisible mending.
