Folding the folder, Kyō-sensu

The paper is folded where the ribs are to be placed. It is first dampened and then folded from one end to the other using a folding mould. Several folded sheets are placed on top of one another and clappers are used to gently tap over the folded line to adjust the shape. The paper is placed inside a wooden frame while still moist for several hours, before being removed to dry.
