Satin Stitch

An embroidery stitch type that creates a smooth, flat fill by laying long or short parallel stitches closely together. Satin stitch produces a relatively smooth tactile surface and is commonly used to fill regions in both decorative and functional embroidery. In tactile graphics, satin stitch variations offer different tactile qualities depending on stitch length, density, and direction, though satin textures tend to feel similar to each other, making it important to limit the number of satin-filled regions in a single tactile graphic to maintain distinguishability.
