Flat stitches are those that lie flat against the fabric surface, creating a smooth and even texture. They are primarily used to fill areas in embroidery with minimal elevation or bulk. Flat stitches are useful for creating neat, polished finishes.
- Satin Stitch: This is a popular flat stitch used to fill areas in embroidery. The stitches are placed close together, running parallel to each other, and when done properly, they create a smooth, shiny surface that resembles satin fabric.
- Long and Short Stitch: This technique involves using varying lengths of stitches to create a shaded effect. Short stitches are placed near each other and longer stitches are used to cover larger areas. This stitch gives a smooth finish and is perfect for depicting gradients or shadows
in designs.
