Well that was an exciting day. My only regret is that I didn't take part. You will see why when you look at these wonderful results below. Maggie managed to fit in three activities into the day workshop. The first was using wool or silk with vinegar water, the second working with papers soaked in alum overnight and simmered in iron water and finally working with cotton soaked in iron solution (ferrous sulphate): all used with plant material.
These first few samples are onto cloth.
These following images are works onto paper.
