Soft purple suede cover with a gentle curve, because you're travelling the curve of the earth, but no mind, for here's the book with pockets, tucks and folds to store all your whimsical moments, photographs, snapshots, letters and reminders, given by tickets, collectables, and all the little things. Because they became the big things.
Or ballet-inspired? Thinking twisting sinew curves, with tutu, corset, ribbons and laces. All balanced on a single point.
