In a ventilated place that is not exposed to the sun and rain, it should be stacked neatly and evenly, and every two layers should be padded with square materials to dry by themselves. Only in this way can they remain undistorted and capable. Don't worry, sun exposure or oven baking will cause deformation, and oven baking is not safe. It is even more impossible to use steam, because steam will increase the moisture of wood. Like I said, it should be enough for a month.
