as above really.
The whole is roughly 6 inches across and unfortunatey crossed a seam between 2 sheets of board. now ive repaired intentional holes before, but in those situations have cut a hole and retained the board that was removed. in this cae there is none. do i have any other option than to buy a new board and batten it in, or is there some remedy i can get away with to patch the hole?
thanks in shame
