Swedish clothing brand Sarva made an indigo waistcoat which is made with natural indigo dyed fabric. Everything is handmade from weaving and dyeing to printing. The print is done hand. Curious how? The stencils are carved by hand in wood or on heavy paper. Then a mix of soya bean flour and slaked lime is applied through the openings of the stencil onto the white pure cotton cloth. When dry, the fabric is dipped numerous times into large tubs containing the natural indigo dye which is extracted from plants in the area. After the desired color is achieved and the fabric has dried, the paste is scraped off, revealing the white patterns on the now blue indigo dyed cotton fabric. Great isn’t it! Authentic workmanship it is.
