Hi everyone, after browsing the various backyard projects on here I've decided to start my own little project.
I'd like to cover an existing colorbond fence with horizontal timber slats and I understand that I need to make a frame to screw the timber panels onto.
One side of the fence is level and shouldn't be a problem putting up the frame, but the rear fence is not level (see attached).
Does anyone have any tips on how to put up a frame against an uneven Colorbond fence?
