• Never use the same pots and utensils for dyeing that you use for cooking.
  
• Wear rubber gloves and use a face mask when measuring mordants and dyes.
  
• Work in a well ventilated area, preferably not your kitchen.
  
• Dispose of used mordants and dyebaths safely.
  

Using natural dyes is not difficult, but takes some preparation. Any fiber that you dye must be clean, or you will be dyeing the wool grease and not the fiber. So scour it well, in hot, soapy water. And rinse out the yarn.

With most natural dyes, it requires a 2 step process. The mordanting of the yarn and then the application of the dye. Many of the natural dyes also need some time to soak (overnight). I usually do this over a 2 day period. I mordant the yarns on the first day, prepare the dye solutions and then dye on the second day. Natural dyes usually require the fiber to be soaked in a pre-mordant bath. The mordant prepares the fiber to receive the dyestuff, deepening, or changing the colour and making it more colourfast.

I used about 1 lb. of yarn, winding off sample skeins, each approx. 10 yards in length. The day before I planned to dye, I pre-mordanted the yarn samples.

For this project, I am using 2 different mordants, to see what range of colours I will get.

Alum/Tartaric Acid Mordant

• Use 10% Alum to weight of fiber
  
• Use 5% Tartaric Acid to weight of fiber
  

Tin Mordant

• Use .5% to weight of fiber
  

Weigh your fiber and the required amount of mordant. Dissolve the tin mordant in the hot dyebath of water. Add clean, wet yarn samples. Simmer for 1 hour. Remove the yarn and rinse well. To save time, you can make larger baths of mordants and pre-mordant larger amounts of yarn, labelling them appropriately, so that they are ready when you want to do some dyeing.
