InvisaFil™ Thread Page

60 Blendable Shades

Since InvisaFil™ disappears so seamlessly into the fabric, you only need to choose a similar colour so it can’t be seen.

Perfect English Paper Piecing

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.

Intricate Stippling & Micro Quilting

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

Quilting Where The Thread Can't Be Seen

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

Hemming with InvisaFil™

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

A Hand Appliqué Dream

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

Truly Invisible Machine Appliqué

A small zig zag stitch appliqués the edge of this leaf down. Invisible machine appliqué was never easier.

Stitch In The Ditch

Or as we like to call it, “stitch in the neighbourhood”, because even if you fall off your path, the stitches are still barely there.

Delicate Machine Embroidery

Lace and fine detail machine embroidery looks crisp and beautiful when using this ultra-fine thread.

Utilizing weight

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

ABOUT INVISAFIL™

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)!

“

Working with Wonderfil's threads has completely upped my quilting game. Decobob and InvisaFil threads are my personal favorites from the line and they have completely changed the way that I piece. The threads are easy to work with, as strong as anything, and positively melt into the fabric. I'll never use another thread for my English and foundation paper piecing for as long as I live!

We are constantly hand stitching our EPP designs for Quilt Market booths and shows . Using InvisaFil has upped our game. It is now to the point where we don't even worry about matching our thread to the background color - InvisaFil just melts into the fabric making our applique and EPP stitches invisible. It is our go-to thread and we don't leave home without it.
