All I can report on this experiment is that the avocado skins and stones failed to colour my clean, undyed wool.
We had fun, had a good chat and had lunch.
We tried reheating and adding vinegar.
We giggled over whether we should pee in a pot and add that. (We didn’t)
Good thing my friend had brought her commercial dyes from Ashford.
The shrinkage was massive after all those interventions.
