100% silk. Bits and pieces of off-white cultivated silk, also known as Mulberry or Bombyx silk. These are waste from the textile industry, and therefore sometimes have debris (like bits of silkworm poo) and could use a good shake before spinning. Noils are easy to dye. We find it's best to take the extra few minutes to tease them open before presoaking (with hot water and soap), to allow for maximum colour penetration. Spinners love to use noils to provide bumpy texture to a spin, carding them in with the fibre of choice. Felters also make use of them for embellishment.
