For in-depth information on hand-dyeing techniques we would recommend Debbie's book Hand-dyed Yarn Craft Projects.
We stock Procion MX dyes which are suitable for use with both animal fibres (hot method) and plant fibres (cold method). Procion dyes can be used on yarn, fabric, fleece, tops, felt, silk, ramie etc. They are suitable for use with all natural fibres but not man-made or synthetic yarns and fabrics.
Please note that the colours shown are for guidance only. The colours obtained from a dye will vary with the strength of the dye solution and the type of yarn being dyed.
