There is a tad difference between personal and coursework sketchbook. Coursework one must hace research and experiments and most pieces annotated and explained. Therefore you have to play up typography and backgrounds.
I'm a bit confused too, if you mean you're looking for inspiration to decorate your sketchbook, I dunno what to tell you. I can tell you that I use these sketchbooks from Barnes and Noble that have a "recycled" cover that you can just draw right onto. I prefer to decorate it with ink drawings. This is what I'm talking about.
Oh, I see. What I am talking about is coursework sketchbook (it has lots of text, like research and annotations). The way we fill those sketchbooks is differs = it's kind of like presentation. ( GCSE, BTEC, A-level courses has this).
I just asked how people decorate sketchbooks of their own.
