The process of discontinuous supplementary weft is one whereby the supplementary yarns are placed in the web of the tabby weave by means of picking out each warp yarn by hand and passing the supplementary weft yarn through them in small or specific areas only. The result is a pattern that floats on the surface of the weave in which many colours can be placed into the design across the width of the fabric. This method is sometimes called “embroidery on the loom”.
