At this time of year the bark just falls off the gums in sheets, making a complete mess of the place but giving you wonderful patches of different colour on the tree trunks. I try to appreciate this when I look out on the debris in the pool!
I collect the bark in old plastic fruit baskets that have holes in them to help the air circulate while it dries, and then they are stored in the garage until I need them. Once you're ready to dye the bark gets soaked overnight in water before boiling the next day.
This reminded me of the piece of silk dupioni I mentioned previously that had been steeping in a mixture of lichens and ammonia for over a year. I brought it out from the back of the cupboard yesterday and got a pleasant surprise.
The fabric had been rolled up and tied along the length repeatedly then scrunched up to fit in the tub in a shibori manner - a once-off creation, I think!
