Yep, I'm a lefty.
My cute little notebook houses mostly recipes that I've tried and liked...my go-tos, of sorts. But it also has detailed notes of the amount of cake, buttercream and fondant I needed and used for a four tiered wedding cake serving 150 and things of that nature. Doodles, stationary I think would look cute as cake, and a running list of random cake musings and tips too.
God forbid I ever lose this thing.
