Dyeing Yarn with Weld Extract
Note before reading: This blog was written in 2017, when I was studying for my MA (hence the Harvard referencing!). Where needed, I have edited these posts to correct any factual inaccuracies. This post was last edited Jan 2025.
If you are interested in dyeing yarn with plants and other botanicals, I run yarn dyeing workshops in Bristol and beyond, where I will show you how to dye British wool yarn a range of vibrant colours. Click here to read more!
Weld (Reseda luteola) is an incredibly popular dye plant producing bright, colourfast yellows. Growing wildly in Europe, it is an easy plant to grow, maintain and harvest. Yielding a yellow colour:
"Weld for yellows and greens was the equivalent of dyer's madder for red: an indispensable dyestuff used by all the early civilisations of Europe and the Mediterranean." (Cardon, 2007, 168)
Above are some images from my trial of using weld extract from Wild Colours. On the sustainable production of the extract, their website states:
"It is produced using processes that respect the environment and comply with organic textile certifications. Our Weld dye extract is an approved dyestuff for the Global Organic Textile Standard (GOTS 4.0)" (2017, online)
I used the extract powder as I have not had the time to grow and harvest my own weld (it's also winter so foraging is difficult!), but going forwards I plan to grow some in my garden, along with other dye plants such as woad and madder. Cardon's Natural Dyes has thorough notes on cultivation. The potential to produce such a vivid yellow with a common native plant is very exciting!
The colour is almost neon and produces great results on animal fibres, with paler results on plant fibres.
