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 looped stitches. Different types of embroidery can also be categorized by their application, such as hand embroidery, done manually, and machine embroidery, which uses a sewing machine for faster results. Each technique offers unique textures and designs, allowing for creative expression in textiles and fashion.
