Embroidery is the art of decorating fabric or other materials using a needle and thread (or yarn). It involves stitching designs, patterns, or images onto the fabric by hand or using a specialized embroidery machine. There are various techniques in embroidery, including satin stitch, running stitch, cross-stitch, and chain stitch, each creating different textures and effects. Embroidery can be used to embellish clothing, accessories, home decor items, and even corporate logos on uniforms. It's a versatile and enduring craft with a rich history dating back thousands of years, spanning cultures and continents.
