Most easily available natural dyestuffs give beige gold or beige.
So discovering something that gives blue is a very useful event.
Black beans. Ordinary ones, from the local supermarket.
They went into the jars of water at the beginning of September, and produced a surprising amount of colour by the following day.
After a few weeks of rather disappointing autumn weather, the scarves I put in were a lovely pale blue.
So the next tasks on the to do list are:
- Try the same beans with electric power in the slow cookers. This may produce a darker colour.
- Try over dyeing fabric that has already been dyed gold. Logically that should come out a nice green. If the blue tint is overpowered by the gold, that one may not work.
