Kirsten picked the icon
The BookKind in our house runs on Kirsten's Cherry Blossom theme, so it deserved its own icon. We drew five book-and-blossom options and she chose the petal stack.
The five we considered
Why this one
Three books stacked flat, in the same pastels BookKind uses for covers it can't find, with the blossom from the top of every Cherry Blossom screen. It reads as a to-be-read pile, which is exactly what the app keeps.
What about BookKind for everyone?
When BookKind is ready for everyone it keeps the WattKind shelf mark. The petal stack stays at home.
