Well disaster over! Andrew decided to call his dad and ask what to do and over his dad came to look at the situation and we can mastic and then cement and then plaster the holes. So no problem. Andrew doing some DIY! Quickly got a photo as evidence that he does DIY honest! So no plasterers needed PHEW! I am off to sugar soap the walls before painting them. woohoo!
Only problem now is that all this mastic, cement and plastering is going to take longer so will still have to wait longer to craft OH NO
