omg you're amazing for pulling all these pics, thank you!! I like the idea of them getting them on the inside of the forearm so they can hold them out next to each other like in some of those pics. It would also be a great spot for their parents to get mad at, since it's not hidden at all times.
I like the roses, the pinky swears, and the roman numerals! Brand definitely would have given Mable final say in what they got, so is there anything that she would have leaned toward more?
I should have lots of free time after work tomorrow so I can finally tackle Brand's bio. I'll link you once I've got a decent amount done!
