Making of True Indigo


The use of indigo for dyeing is old as history, its geographic spread initially as wide as the habitats of the many plants that produce the dyestuff. In temperate ancient Europe and Central Asia, the woad plant Isatis tinctoria was the source; in Japan, Dyer’s Knotweed Persicaria tinctorium, was – and still is – used. But it is the tropical plant Indigofera tinctoria that has come, through trade, to predominate.

Making of True Indigo

With all the plants the process of dyeing is chemically the same, involving the breaking down of the leaves through composting, fermentation or decomposition to extract the pigment – which may be left in dilute form or precipitated out to be dried into blocks or powder. Beyond this essential similarity of process, though, are hundreds of regional and arcane variations – and all are demanding of time, labour, resource, precision and skill.

All share, too, the magical moment when the cloth or yarn is finally pulled from the de-oxygenated liquid of the dyebath into the air – and emerges a yellowish green colour then, as it contacts the oxygen in the air, gradually turning to the prized deep blue.

So where does the beauty of true indigo lie? Firstly, it is a beautiful blue, deep and unmistakable. More than that, though, it is alive – however skilled the dyer, the thousand and more natural variations in each dye lot will mean it is never entirely uniform (and therefore flat) but always a little uneven (and therefore beautiful). And that liveliness is reinforced by the way it fades with wear and washing – so subtly, its beauty increasing while it ages. It is a good example of perfection attained through imperfection.

Then we love it for its variety of colour and texture – from blue-black all the way to a clear, age-washed palest blue. I’ve seen tribal indigo cloth from northern Burma and southern China that’s black-purple or purple-bronze glazed to a waterproof gloss with egg white; or finest, floaty pale blue shibori silks from Japan.

Beyond that, we love indigo for its history, its cultural diversity: exquisitely beautiful resist-dyes from Japan: ajrakh block printing from Gujarat; bold tie dyes from Cameroon, Nigeria, Burkina Faso; beaten indigo head cloths from the Saharan Tuareg; deep blue, pleated linen biaudes – smocks – from rural France. While regional traditions are readily identifiable, the same techniques occur again and again – tie dyeing, resist dyeing – so curious similarities crop up all the way from from Northern Europe to South East Asia, the local manifestations opening windows into the predilections and character of the maker. Again and again I’m amazed by the effort and skill that goes into these hand-worked fabrics – that everyday, unselfconscious aspiration to beauty.

True Indigo

We use indigo for tough, workaday denims; for light and heavy linens; for cotton jerseys. We use it, woven for us in Italy, as a component of wool and cotton coatings. We use it in beautiful heavy cotton herringbones and double cloths woven for us by a wonderful mill in Japan, thoroughly traditional in its love of the craft, thoroughly modern in its painstakingly green production. We’re very happy – so happy – to feel that, in however small a way, we are taking part in a continuing tradition, paying homage to the artisanal masters of the past and present.
