The white part of the thread core is made as large as possible so that it can be easily hit.[Indigo: 13.5oz selvedge] The yarn is made by spinning rough raw cotton, which is hard and rough in both warp and weft, by a method (strong twist) that gives a rougher feel.
The uneven shape also has a natural appearance that was difficult to express with thick threads. Dyeing is done with a special dark colour that can be expressed with indigo. You can expect severe discolouration daily.
