The Yew dyebath

All parts of yew are poisonous so, rather than dyeing with yew in the kitchen I used an old slow-cooker in the cellar (these work very well whether the dyestuff is poisonous or not!).  This dye bath hadn't yielded much colour after simmering for a couple of hours so the twigs were soaked and simmered on and off for 3 days.

Lovely warm browns.  Again:  on silk, basic colour, acid modifier, alkaline, copper and iron.
