The Extended Tunisian Simple Stitch (EXTSS) is a variation of the Tunisian Simple Stitch (TSS), but with an extra chain-like extension. In this stitch, each row is extended by one extra chain per stitch during the forward pass. This makes the fabric taller and looser than regular TSS.

Thanks to this extension, fabric created with the Tunisian Extended Simple Stitch has a softer drape and a more open, airy texture. Another big advantage is that the EXTSS helps reduce curling. Because of these advantages, it’s a great choice for projects like garments, scarves, or lace-like designs where you want fluidity and movement instead of stiffness.
