How to Make a Wet-foaming bag

The technique of ‘wet-foaming’ makes use of the properties of case leather, whereby the leather is wetted in water, reshaped and then allowed to dry and transformed into that shape. Generally, this technique is often employed for shoes and harnesses.

To adopt this technique for bags, we took a hint from the production methods of Japanese drums. The angle of the roundness was adjusted many times, and while looking ideal sharpness, we succeeded in expressing a unique roundness that cannot be achieved by sewing, resulting in a new iconic bag that has never been seen before.

Processes

A normal bag is made immediately because only the leather is cut before sewing.
Wet-foaming takes over a week. Shaping vegetable-tanned leather takes time, but the craftsman wants to create something good.
Deciding the design
In order to achieve the best possible sharpness, we try different approaches and think about what is most practical and convenient.
Making wood molds
Turn the design on the desk into a real bag by making a wood mold for the leather.
Cutting the leather
Cut leather larger than mold.
Wetting the leather
Pressing the leather on the wood mold
Strike the leather against a tree
After the leather has been shaped to some extent, strike the leather against a tree to remove the mold.
Drying about 3 days
Removing it from the mold.
Remove from the mold and let the inside dry for about 3 days.
Cutting the excess leather.
