First fine day I've had time to do this job. Indian ink in my hair, on my face and all over my clothes, but it is successful and quite quick to do. This number of teasels should cover one pole.....
Interestingly the shellac in the ink holds the teasel bunches together which is advantageous as the teasels are old and potentially crumbly. Once completely dry I'll have to find them a new storage place!
