The fabrics and yarns used in traditional embroidery vary from place to place. Wool, linen, and silkhave been in use for thousands of years for both fabric and yarn. Today, embroidery thread is manufactured in cotton, rayon, and novelty yarns as well as in traditional wool, linen, and silk.Ribbon embroidery uses narrow ribbon in silk or silk/organza blend ribbon, most commonly to create floral motifs.
Surface embroidery techniques such as chain stitch and couching or laid-work are the most economical of expensive yarns; couching is generally used for goldwork. Canvas work techniques, in which large amounts of yarn are buried on the back of the work, use more materials but provide a sturdier and more substantial finished textile.
In both canvas work and surface embroidery an embroidery hoop or frame can be used to stretch the material and ensure even stitching tension that prevents pattern distortion. Modern canvas work tends to follow very symmetrical counted stitching patterns with designs developing from repetition of one or only a few similar stitches in a variety of thread hues. Many forms of surface embroidery, by contrast, are distinguished by a wide range of different stitching patterns used in a single piece of work.
