Which I do all for most of the year. In the spring I collect Bracken fronds, gorse and comfrey which is also known as knit bone. Nettles I collect when I need them and they dye an array of colours from wonderful browns to greens. In August I pick Bog myrtle and heather, both dye beautiful yellows and the smell they produce is intoxicating.
It starts by hunting and gathering.

Dying the wool is a very lengthy process. The wool I use is Blue faced Leicester and very soft, perfect for shawls and scarves. I also use worsted wool which is tough and great for those projects that see more wear. The wool hanks are washed to rid them of any lanolin, the natural grease on the wool. The hanks then need to be simmered in a mordent which is a metallic compound which is either alum, iron or copper to make the dye stick.
The dye is extracted by boiling the dried or fresh plant for an hour or so. In some cases such as gunnera root or iris root the process can take days to extract a deep colour and the roots need to be pounded and soaked first. The mordented wool is then added to the dye vat, steeped for an hour and left to cool over night. The results are always exciting and some of them are shown below.
