Frankie's in Baby Sophomore Potions on Monday and Friday.
To her, Amortentia smells like bakery early the morning, before any of the customers arrive, ovens all stoked up and pastries just starting to rise. (And now she's hungry.) It smells like trees and leather and sports equipment and the paints they use on the walls of the Sophomore cabin. And she'd very happily tell people if asked - though she also has some quiet opinions on the whole potion being mildly akin to a magical Molly.
She smells faintly like paint and largely like Bristol Board and charcoal/graphite pencils. With a hint of vanilla frosting and coconut shampoo.
