Wool & Viscose
Wool is one of the best yarns for making rugs. Being a natural fibre that feels warm and soft underfoot. Wool rugs do shed, and the amount of shedding depends on the origin of the wool, length of its fibre and diameter of the fibre and its processing into yarn. Wool has some fire-retardant qualities. Note that some people can be allergic to wool.
Viscose is a fibre made from regenerated wood cellulose. Viscose rayon is structurally similar to cotton, a soft man-made fibre commonly used in clothes, upholstery and carpets.Viscose has very similar properties to silk, it is shiny and soft but it does not have the same elasticity as other yarns and if used in large quantity. Viscose is often mixed with wool or other yarns to give more elasticity it.
