Need: A small piece of plasterboard and/or some plastering tape

Hi,

I need a small piece of plasterboard; about 40cmx25cm to repair the wall where the plumber had to make a hole to access pipes. It's not worth buying a whole sheet of plasterboard for just a little patch.

If you have a little bit of plastering tape too that'd be fantastic if not, that's not a big deal, I can buy that.

Thanks in advance.
