There's no way we'd ever need upwards of eighteen different notebooks, but every time we see the Paperthinks Recycled Leather Notebooks ($18), we want to buy them all. Think of how perfect they'd look displayed in all their rainbowed glory! The shelf in our living room would thank us, even if our pocketbooks wouldn't. Can we justify the purchase if we say we'll commit to writing the next great American novel in them? Our scribbled penmanship will look so artsy sandwiched between rainbow-colored leather!
