Plywood Sheet: Sawn Veneer Cross-Laid with Hide Glue
Plywood is thin wood laid in layers with the grain of each crossing the next, an odd number so the sheet stays flat; it splits less and swells less than solid board. Glued with hot hide glue, the woodworking glue of veneering since antiquity, and pressed flat overnight.
The picture: our diagram of the crossed plies.
