February 6, 2010 - Vauxhall City Farm.
I attended a dye workshop with Amar, where we got to learn informally about the natural dye process. It made a little bit more sense seeing it as opposed to just reading about it in books. We dyed wool yarn in Weld, Tansy, and Golden Rod.
First we put our yarn in a mordant, alum, which can be found in local supermarkets. We simmered the yarn in boiling mordant water for 45 minutes. This can also be done overnight in cold water and alum. After the mordanting process, we put the yarns in three different dye baths. Those were then simmered for 30 minutes. The results of those were:
1. weld - bright yellow
2. tansy - yellow green
3. golden rod - orange yellow.
Overall a good experience. Can't wait to try it ourselves in the dye workshop in the college. Don't know how successful we will be because we have to make a concentrate of the dyes. As in, take the dried marigold and boil and simmer it for 1 - 2 hours to get a concentrate before thickening it will indalca or manutex, a seaweed thickener.
