Multi-Purpose Dye is ideal for small items containing nylon and Lycra® e.g. stretchy tops, underwear and decorative items such as grasses, feathers and buttons. Suitable for cotton, linen, viscose, wool, silk, nylon and Lycra® (elastane). NOT suitable for pure synthetics (except nylon), polyester/wool mixtures, or fabrics with special finishes. Multi-Purpose Dye is not colourfast so garments should always be washed separately. One tin is sufficient for up to 250g/8 oz dry weight fabric.
