place. Tufting frames are generally constructed of wood, with carpet tacks or grippers around the edge to hold the primary backing fabric in place. Eye hooks are an important addition to a tufting frame, they are used as yarn feeders and work to keep the tension consistent. The frame must be sturdy and can be either freestanding or clamped to a table top. It is important to keep pressure and speed consistent when tufting so that the amount of yarn per square inch of the fabric is consistent. Any mistakes in the design can be corrected throughout the tufting process by simply pulling out yarn strands from the primary backing fabric and re-tufting the area. Designs can drawn directly on to the primary backing fabric, this can be done freehand or with the aid of a projector. After tufting is completed, the tufted piece requires a coat of latex glue on the back in order to keep the tufts anchored in their place. Latex glue is beneficial for tufted pieces as it provides flexibility and dimensional stability. The piece should remain stretched on the frame until the glue has finished drying to avoid loss of shape and the possibility of mildew. A secondary backing layer is then applied, providing further dimensional stability and protection for the finished piece as well as improving its appearance. A wide variety of materials can be used for the secondary backing fabric depending on the intended use of the piece. Felt, canvas, drill and other harder wearing materials can be used for floor rugs, however backing fabric for wall hangings need only be aesthetic, as it is only required to cover up the glue layer and does not need to be hard wearing. Wool is the traditional fibre used in pile tufting and is considered to be a high-quality material, especially for pieces designed to be used in high-traffic areas. Wool can be spun into yarn by two systems, either woollen or worsted. Worsted yarn is more favourable for tufting when the finished product will be used in high-traffic areas, as it produces a hard flat surface that is tightly woven together. This is due to the tightly wound, fine yarn which is created in the worsted process. In comparison, woollen yarn used in tufting encases more entrapped air in the finished product and a bulkier finish. Different yarn fibres can be used depending on
