Water sedge that we use has pretty shiny surface which makes it difficult to dye and colour. To prevent colour falling to your cloths, please avoid direct contact with white or light colour cloths. The loss of colour will fade or stop after a few uses. In case the colours transfer to your cloths, please note that it can be removed or cleaned with regular wash.  We currently use chemical dye to make sure the fixation of the colour. Natural dye is still being researched. We will implement it as soon as it’s successful.
