How is timber plywood use for decoration as a written project?
If I’m understanding your question correctly, plywood is a manufactured piece of wood, its several pieces of veneer cut from logs and laminated together, the veneers are layed cross-grain to each other to make a stronger panel, (exception: bending or formable plywood is not) there are several grades of plywood, the best being cabinet grade made from hardwoods, construction grade has some voids and patches, you also have arts and crafts or craftwood grade, this grade won’t have voids and is made from soft wood. Its the craftwood that you would use for making decorations, emblems, letters, symbols, etc. there is no voids in the edges once cut. It is also wise to put a protective finish on after your paint, stain, etc..
