Yea, like an actual wall which can stand. Or anything which is dry wall material? Because I have a table tennis table at home and I am the only one who plays table tennis in my house and my basement isn't fully furnished and has that pink insulation stuff so i was thinking about just buying something which is of the dry wall material (because that is the material which the table tennis balls bounce off of properly) and then just placing it on the other side of the table. Any ideas on where I can buy that or how I can create my own table tennis return board?
