Mouse in the House captured our interest at Playtime New York with a wonderful earthy toned knitwear collection. So how do you create this muted colour palette? Natural Plant Dye, a process that has been in practise since ancient times, with the earliest written record of the use of natural dyes dating back to 2600 BC in China. Mouse in the House let us look at the dyeing process of their producers in Nepal and we discover more about this interesting process of making natural plant dye knitwear. 

Most of the dyes for their collection are sustainably sourced from the forests that surround the village where their knitters live, in Nepal. A few have to be ordered from India, but their Nepalease makers are quite resourceful and careful with what they have available locally.

Mouse in the House - Natural Plant Dye
Natural dyes can be sorted into three categories: natural dyes obtained from plants (indigo), those obtained from animals (cochineal), and those obtained from minerals (ocher). Although some fabrics such as silk and wool can be colored simply by being dipped in the dye, others such as cotton, require a mordant. In Mouse in the House’s case they focus on using natural plant dyes.

A mordant is an element which aids the chemical reaction that takes place between the dye and the fiber so that the dye is absorbed. Containers used for dying must be non-reactive (enamel, stainless steel.) Brass, copper or iron pots will do their own mordanting. Not all dyes need mordants to help them adhere to fabric. If they don’t require mordants, such as lichens and walnut hulls, they are called substantive dyes. If they do need a mordant, they are called adjective dyes.

Common mordants are:

  • ALUM, usually used with cream of tartar, which helps evenness and brightens slightly.
  • IRON,  which saddens or darken colors, bringing out green shades.
  • TIN, usually used with cream of tartar, which blooms or brightens colors, especially reds, oranges and yellows.
  • BLUE VITRIOL, which saddens colors and brings out greens.
  • TANNIC ACID, used for tans and browns.

Madder is used by Mouse in the House for Aw17 and is a good example of a commonly used natural plant dye. It is obtained from the madder plant and produces a red colour. To collect the Madder, the plants are dug up, the roots washed and dried and then ground into powder. The dye was popular during the 19th century, then in the mid-1800s a synthetic substitute was developed which is commercially used now. This video shows the madder root used for dyeing the pink color called “Sunrise” used in their collections.


Mouse in the House produce their collection in Nepal working with a group of talented nepalese makers who earn a living wage significantly higher than other fair-trade organisations. It’s obvious that they deeply value the importance of seeking out high quality, sustainable, natural materials that are produced in ethical ways with respect to humans and the planet.

Their Products:

  • Hand-dyed yarn using sustainably-sourced plant dyes.
  • Pure australian merino wool, hand-plied yarn.
  • Wooden buttons locally made from Allo – a giant nettle that grows wild in nepal’s mountains.
  • Hand-felted, undyed felted wool balls.

We have also seen vegetable and plant dying used by the label UPA for their SS17 collection but in their case using silk.  The process is fascinating with all the possible variations and tones of colour that can be produced. The makers in Nepal certainly know their craft in great depth, and in turn the modest modernity that Mouse in the House injects to the collection with their general ethos towards producing children’s clothing makes for a very wonderful collection for AW17.
