How to Make Fall Reading Extra Cozy
Let’s be honest: a cozy book deserves a cozy setting. Light your favorite fall-scented candle, grab your fluffy robe and socks, and sip something deliciously warm. As you know, we’re all about detail, and this fall we think accessorizing is the ultimate indulgence. Our Boutique is your one-stop shop for all your bookish needs.
We are loving our cream-colored “Ask Me What I’m Reading” book sleeves with their elegant purple font. These book sleeves also feature an incredibly soft, vegan leather exterior with an elastic pen/highlighter holder, a small, zippered pocket on the back, an extra-large (think Crescent City, two-to-three paperbacks, or a 10" tablet + a book) lined interior, and an elastic button closure at the top.
And let’s not forget about our incredible phone case covers. Pure bookish delight! We have endless design options, and we think you will love this exclusively designed phone case inspired by Mary Poppins, by P. L. Travers. This adorable phone case features a floral design on the front cover with the silhouette of Mary Poppins flying with her umbrella and bag over the London skyline. The back of the phone case features a stack of tea cups and the quote, "Practically perfect in every way."
