I have spent flipping ages making 2 roman blinds for my mum's new build house. I have a bracket that needs to go in to the window recess, I have to drill these to the top of the recess.
The first hole was ok, easy for about 1/4 of the wall plug length then really hard but suddenly popped through.
On the left I just cannot make the hole deep enough, I think I'm hitting metal and 4 holes later I am grumpy and have buggered up my mums wall! What do I do now, I need help.
