Most blockprinting is done using dyes that need fixing with battery acid. We used these dyes for many years, but once we realised this we switched to using 'pigment' dyes. These dyes are the most low impact dyes we can find, however there are two downsides to them 1) a slight, or sometimes stronger smell that comes from the binder that is used to fix the dye to the cloth. this disappears after a couple of washes. 2) on the patterns that have more dye on the cotton the cloth can feel a little stiff but after washing becomes lovely & soft for many years use Blue Sunflower Duvet Cover Hand Block Printed On Organic Cotton
