The first step in the traditional fibre extraction process often involves hand-picking or harvesting the plant material. This is done when the plant reaches the optimal stage for fibre extraction, ensuring the highest quality and yield.

3.2 Retting
Retting is a natural process where plant material is soaked in water to break down the non-fibrous components, leaving behind the usable fibres. This can be done in still water, such as ponds or slow-moving streams, or in dew retting where the plants are left in the field to be naturally soaked by dew and rain.

3.3 Beating and Pounding
After retting, the softened plant material is subjected to beating or pounding to further separate the fibres from the remaining plant tissue. This can be done using traditional tools like mallets or even by foot, as seen in some cultures.

3.4 Scutching
Scutching is the process of further cleaning and separating the fibres by hand or with simple tools. This step is crucial to remove any remaining impurities and to align the fibres for spinning or weaving.

3.5 Spinning
Once the fibres are cleaned and aligned, they are spun into threads or yarns. This can be done using a traditional spinning wheel or by hand, depending on the local techniques and available tools.

3.6 Weaving and Processing
The spun fibres are then woven into fabrics or processed into various products such as ropes, baskets, and paper. Traditional weaving techniques vary widely across different cultures and regions.

3.7 Cultural Significance
