Natural Dyers Academy ~ Module 4 Yellow

Natural Dyers Academy ~ Module 5 Yellow 

group of yellow dye plants
Most plants will give you a version of yellow and beige and are usually the first dye one will discover when foraging for dye plants for the first time.
I remember my very first mystery yellow dyes, almost 20 year ago now - Conker or horse chestnut flowers and stalks, as well as wild growing Alexanders (Smyrnium olusatrum). I was very happy with my yellow yarn, especially the Alexanders can produce stunning yellows and greens with iron - but not always. The horse chestnut flowers weren't that amazing, but gave a soft yellow on wool yarn - but not for very long.
From sticky willy to lovage, from dock leaves to mint - I tried a fair share of plants on different materials. I was particularly after greens, which natural dyer isn't? By combining yellows with iron, I achieved some gorgeous greens with sage, lovage and mint, but did any of them last? Yes, some of them did, some of them occasionally and some not at all. Why? 
  • In this module, I will explain why some yellow dyes stay and why other don't.
  • Which yellow dyes are the best ones to use in your studio in terms of brightness, colourfastness and availability.
  • We will look at the history of yellow as well as the use of each yellow dye plant in the past; where it can be found, origin and of course, recipes.
