On Saturday morning I harvested dandelion flower heads.
In the evening I boiled them for 30 minutes to make a dye bath. I followed advice from a varieity of books on the subject. I chose to use silk because apparently dandelions dye animal fibre better. I wish I had put a little wool in as well to see if there was a brighter result. I mordanted two kinds of silk with alum and cream of tarter, following instructions. Dye stuff and flowers had to be in equal amounts so I used 6 inch pieces of fabric. The fabrics had to be brought to a simmering point and then be allowed to cool down again, remaining in the liquid over night. On Sunday I combined the fabrics in the dye and brought everything to a simmer and kept it simmering for an hour, but again the fabrics had to be allowed to cool and sit in the 'dye' overnight. This morning, nothing magical happened to turn the tan fabric yellow.
Dyeing with natural dyes is labour intensive, slow, and unpredicatble but I knew that. This is a process I have wanted to DO for years. I am posting this as evidence of my own learning.
Any advice on getting yellow rather than tan?
