Some black trousers I'd recently bought needed shortening, so everything was set up on my work bench.
As the sun was shining in through the window (hey whats this? sunshine?), believe it or not, that actually made it quite difficult for me to see what I was doing, so a little bit of re-arrangement was called for.
Having moved the bench round through 90 degrees so the sun was coming in on my left side, it was much better.
I do so love my studio.
