Hmm… What to do with that extra gallon of teal paint?
If you make a mistake, do it louder and repeat it until it no longer seems like a mistake. And at least the floor shouldn’t cave in. Lots of crazy looking wiring as well. There are better ways to install a load bearing beam.
Nobody else could make this work one-handed. Seriously, I’d love to hear the reasoning behind installing the doorknob this way. At least you don’t have to worry about whether the door is right or left handed.
