I needed a quick present for a niece and, kind of wanted to try saddle stitching after seeing everyone here talking about it. I was able to adapt @jiva 's design to fit an inexpensive sketchbook of the same general size.
This is a “throw some art on it” rough draft but, I like how it came out enough that I am likely to do more.
I used the Saddle synthetic leather from Johnson. Engrave and cut was quick and easy once I got the settings sorted.
