text: Embroidery can also be classified by the similarity of its appearance. In drawn thread work and cutwork, the foundation fabric is deformed or cut away to create holes that are then embellished with embroidery, often with thread in the same color as the foundation fabric. When created with white thread on white linen or cotton, this work is collectively referred to as whitework. However, whitework can either be counted or free. Hardanger embroidery is a counted embroidery and the designs are often geometric. Conversely, styles such as Broderie anglaise are similar to free embroidery, with floral or abstract designs that are not dependent on the weave of the fabric.

  Materials
  A needle is the main stitching tool in embroidery, and comes in various sizes and types. The fabrics and yarns used in traditional embroidery vary from place to place. Wool, linen, and silk have 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.
