as promised here is the photo of my wool dying efforts! not such a great photo but eh I'm getting better. I did one evening worth and then one afternoons worth to get this much. I'm in hospital tomorrow for an operation so I knew I'd be needing something to look forward to for when I get home after the day surgary.
Anyways out of four food colors I sure did get a lot of shades, a lot of it is just trial and error, mixing how you want and seeing how it goes!
