Inspo - making my booklets more fun!

My main challenge is to make my booklets more fun and less authoritative, so i've been looking for some inspiration. I want these booklets to be something the participants can collect and keep in one place to refer back to as well.

simple things like, changing my font, changing the colours, rounding edges, and having separate pages attached by book rings could make these a lot more fun.

Sketching ideas for the booklets and how a sticker chart or customised covers could be incorperated.
