How to extract the dyes:
Soak the dried flower heads in a pot filled with 4 litres of warm water for 30 minutes.
Heat the dye bath to +70 °C, well below the boiling point.
Adding one tablespoon of washing soda or 0.5-1 dl of wood ash lye can improve the colour extraction and modify the colour from brown to orange.
Steep the flowers for 30 minutes to extract dye.
