Harvesting takes place when the bamboo begins to bud. Leaves and buds are removed and the bamboo stems are cut to a length of 1.50m to 2m. The green bark is then removed after or not, a bath of water (the operation is called "killing the green"). The pieces of bamboo are cut in their length and assembled into bundles of 25 kg. The bundles are then immersed in water for one week and then cut into bundles of 50cm length. These bundles are immersed in pits filled with lime for 1 or 2 months. The bamboos are then rinsed with water to remove any lime; this rinse lasts 10 days.

The bundles are then boiled in water for 5 days to soften them and then sprinkled with urine and left to fermentate for 15 days. The bundles are then placed back in the pits filled with water and removed when required but generally, not before six months.

Another technique is to cook the bamboo in an alkaline solution of ashes or lime water during 4 or 5 days; this operation allows the elimination of embedded substances and also whitens the fibers.

To prepare the pulp before forming the sheets, a first beating is done in a stone grinder until obtaining a clay consistency. Previously a trip hammer was used. Currently the pulp is poured into a sort of hollander beater without wheel, where it circulates; this operation allows the removal of large pieces which float on the surface.

The pulp is then poured into the tank, dispersed into water and mucilage is added which will work as formation aid of the sheet. The nature of the plant that provides the mucilage varies according to the region.

The sheets are formed in a single scoop on a movable screen. The sheets are placed in stack with an inserted thread. At the end of the day, the stack of paper is covered with a board and placed under a charge or in a lever press.

The next day, the sheets are detached from the stack and brushed on the surface of a vertical double brick wall heated like an oven; they can also be brushed on a board or placed on the ground.

The paper may or may not be sized with wheat or rice flour paste: the glue is brushed on both sides with a broad brush. The operation can be done at the time of drying.

It is grown from cuttings. After two years, the branches are cut and tied in bundles which are steamed for several hours in order to peel the bark. Harvesting takes place in autumn or in early winter.
The bark is then retted for several months in water so that the dark outer bark can be easily removed from the white inner bark. The remains of the black bark are scraped to keep only the whitebark.
The bark is cooked in a weak alkaline solution (wood ash or sodium carbonate) and is then bleached in the sun (or recently using hypochlorite). It is then cooked again and again sun bleached. The bark is placed on the mountainside, on rocks or on the banks of rivers. This bleaching takes several months of exposure by turning the fiber bundles.

The straw pulp previously prepared (see rice or wheat straw) is added to the bark fibers and the whole is beaten in a Hollander beater, or in the past using a water beater.

As the sheets are large (70/140cm), they are manufactured by two workers. The stack of sheets is pressed in the late afternoon. The sheets are then dried on a heating surface.

Variation: The bark and the straw are soaked in a lime water bath for a few days and then cooked in a weak alkaline solution (wood ash or sodium carbonate).
