Shoutout to the neighbor kid who showed me the tape trick for box corners
I was building a castle tower in my driveway in Sacramento last weekend and the walls kept folding in on themselves, and this 9 year old from two houses down watched me struggle for 20 minutes before saying "you gotta tape the inside corners first, lady." Tried it and the thing finally stood up on its own, so now I want to know what other basics I am missing.
