Dyestuffs from the freezer are having to make way for meals that I'm gradually making and storing for the busy days ahead. There was a bag of elderberries collected a year ago. It seemed a shame not to use it so I coooked up the whole lot and dyed some silk, as dark as it would go. It turned the seasonal colour of crushed grapes.
As a typical berry dye it's sensitive to pH and changes to almost red in acids and bluish grey in alkalis (and back again - the little swatches were dipped completely in baking soda first and half in vinegar later).
The colour will suit another piece for the new series... if I still have time to make it.
