That day I realized I'd been using painter's tape backwards for 5 years
I was patching drywall in my hallway last Saturday and my buddy Mike walked in, saw me putting tape on, and just started laughing. He said 'Dude, you're supposed to fold the edge, not leave it as a straight line.' I'd been doing it the lazy way since my first apartment in 2019, always getting fuzzy lines on my trim. Now I fold a tiny bit under on the edge and the lines come out razor sharp. Has anyone else had a basic tool trick that took way too long to learn?
