Close-up of InvisaFil 100wt invisible polyester thread spools

The fine thread allows for small detail work and dense stitching that keeps the fabric soft and flexible.

Let your stitches stay unseen when doing EPP. The fine thread allows the pieces to sit snug and flat with no stitching to be seen.

Colour IF718 in a light grey was stitched across multiple fabric colours, and it blends perfectly into all of them.

The edge of this leaf was hand appliquéd with InvisaFil™. The fine thread allows appliqué to lay flatter while disappearing perfectly.

InvisaFil™’s fine properties are especially perfect for small intricate embroidery designs.

Did you know? You can use InvisaFil™ to hem lightweight sheer fabrics using a serger or sewing machine.

Lace and fine detail machine embroidery looks crisp and beautiful when using this ultra-fine 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 colours with a matte finish, so you can choose how much want the thread to show (or not at all)!

How does InvisaFil™ stay invisible?

It’s 100wt, 2-ply cottonized polyester construction creates ultra-fine stitches that blend seamlessly into fabric, with a matte finish to avoid unwanted shine.

Is 100wt thread strong enough for quilting?

Yes! InvisaFil™ is a cottonized polyester, which allows the thread to be strong yet fine. This type of polyester also does not stretch and behaves more like a cotton, making it an excellent candidate for quilting when you want the thread to blend or disappear, leaving only the texture of the quilting to be seen.
