I am trying some more dyeing in the environment.
First I pre-mordanted a wool blanket in alum and cream of tarter but I'm not sure I had to do that.
Then I headed outside, negotiated the right distance to walk around this family without being attacked, and went on into the forest...
...down to the bog.
I dropped the blanket into the water...
...and stomped on it.
The idea is to leave it for up to a year with occasional liftings to oxidise what is going on.
It is an old Scandinavian technique for getting shades of black on wool.
