The rope at the (maybe) Lake of Tears. When he pulled it and the water gurgled, for a few seconds I thought he'd pulled the plug out and the water was gonna drain out of the bottom of the lake lol
I have a roll down blackout curtain that does most of the heavy lifting. At the edges, to block the light that cones out from the side, are panels cut from my old roll down curtain that broke - along the top is part of a duvet cover to block out light coming out up there.
At the bottom is an old scarf to block light at the bottom. And over top of it all are hanging semi-blackout curtains. Last pic is the result.
