Let me introduce Old Magic notebooks from Favoring Brave.
Each book includes a sheet in the back with information about how the book was made, how old it is, where it was found and what book number it is - book number being the number in which it was made. That means I'll be able to keep track of how many I make total over time!
The first five are available on Etsy now! Here they are - click the picture for a closer look.
