I’ve been making little pocket notebooks. Moleskine Cahier knock-offs for guild giveaways. For my own carry around, I have always just made it plain, sans back pocket, and stapled, instead of sewn. (Similar to my project journal except 3.5″ x 5.5″.) I do have to say that the sewn binding make a much tidier notebook. But mine are meant to be tossed in my bag and used, so I don’t much care.
The top white one (with pink flower) was my sample before I started on the guild notebooks (black sheep, get it?). The smaller white notebook in the lower right was made with leftovers.
