IT'S SO EASY: 10gm of dye powder with 10 Tablespoons of white vinegar will dye 1kg of fibre to full shade. For smaller quantities 1 level teaspoon of dye powder with 2 Tablespoons of white vinegar will dye 200gms of fibre.

Please wear a mask and gloves when mixing the powder, and gloves when in liquid form. Use dedicated utensils - not eating cutlery.
