First order of business this morning was to remove the old backdrop so I could evaluate how best to chop 70mm from the top of the boards. I’ve fretted over this step for a couple of weeks. It would seem logical to simply cut the required slice from the bottom of the board (this is 6mm mdf btw) but doing this would mean I’d lose all the trees and foliage down below the layout edge. I needed a way to remove the 70mm (21/2″) from the top of the sky. I wanted to lower the backdrop, not lower the horizon.
