Embroidery techniques involve various methods of decorating fabric using needle and thread. Common techniques include cross-stitch, where X-shaped stitches create patterns, and satin stitch, which fills shapes with smooth, flat stitches. Other popular methods are backstitch for outlining and chain stitch, which forms a series of connected loops. Different types of embroidery can also be categorized by their application. Hand embroidery is done manually, allowing for intricate designs, while machine embroidery uses sewing machines for faster production. Techniques can vary by culture, with styles like Japanese sashiko and Mexican folk embroidery showcasing unique patterns and traditions.
