My buddy told me my cardboard castle looked like a plain Amazon box, so I started cutting crenellations
My friend Jake came over to see the fort I built for my kid's birthday and said it looked like I just flipped a fridge box upside down. That stung because I'd spent two hours on it. So now I cut real crenellations along the top and score brick lines with a dull box cutter before painting. Anyone got a trick for keeping the flaps from sagging after you cut them into battlements?
