Before boarding a plane in South Carolina yesterday, I was amused to see these in an airport gift shop:

South Carolina: Where even the adult coloring books are biblical…
I guess they wanted to avoid those demonic “mandala” patterns.
On a side note, isn’t the whole point of adult coloring books that they’re a little more challenging than what you did as a kid? Isn’t that what allows you to relax, have fun, and create something pleasing to the eye? Because, subject matter aside, these “hymnspiration” books looked like something a kindergartner would get bored coloring.
