Embroidery is the art or handicraft of decorating fabric or other materials with needle and thread or yarn. Embroidery may also incorporate other materials such as metal strips, pearls, beads, quills, and sequins.

A characteristic of embroidery is that the basic techniques or stitches of the earliest work—chain stitch, buttonhole or blanket stitch, running stitch, satin stitch, cross stitch—remain the fundamental techniques of hand embroidery today.

Machine embroidery, arising in the early stages of the Industrial Revolution, mimics hand embroidery, especially in the use of chain stitches, but the "satin stitch" and hemming stitches of machine work rely on the use of multiple threads and resemble hand work in their appearance, not their construction.
