From Gingercake:
"This pattern was created to revive and rejuvenate those old binder and notebooks you have sitting around the house (or new ones from the store!). It is also great for personalized, beautiful, & useful handmade gifts. Store bought journals beware! This pattern makes regular notebooks so lovely you will be covering every spare notebook in the house.
The notebook slipcover is designed for you to be able to cover a binder or notebook of any size. It creates a thick and substantial cover that is also completely washable. This design gives a snug and professional fit to look beautifully handmade."
