We make cotton leather from things we have around us. By chance, we received a wine cork stopper, so we powdered it, mixed it with natural rubber, and baked it.

The heat was too strong and burnt the material, but it turned out to be a somewhat strange feeling material.

If we make adjustments, we think the material will be adequate. Nevertheless, it is a brownish color again. We are in a hurry to make a transparent lacquer so that we can develop colors (color variations) as soon as possible.
