If she sells out before you can nab one (they’re only $25) or you like the idea but they aren’t exactly your style, consider making your own. Get a chalkboard and then use acrylic paint markers to add your favorite text.
I’m someone who is allergic to chalk dust, so when I was a teacher I always used chalk markers. Even if you aren’t allergic to chalk dust, these are great for keeping your hands and desk drawers clean.
