I just loved this spread from the Moleskine sketchbook of Finnish artist Paivi Eerola, posted on her website Peony and Parakeet:

Here’s some of her thoughts on art journaling:

For me, art journals are little more than just sketchbooks. I like to call them “idea books” as I often process my ideas further when I am working on the page. I don’t always make one page on the same go, but work with it several times, adding more ideas as the page progresses. However, I have quite low expectations on how my pages will look. They are not pieces of art but more like collections of ideas to me.
…
My art journals are not chronological diaries but random visual notes that I process to full images. I can make a quick sketch of a rose one day and then continue the page with painting on the other day. When I am working with a new art class, I use art journals to record my visual ideas and practice the techniques. I also see creating art journal pages a route to bigger paintings. When I paint on canvas, I use the ideas that I have come up with when making the pages. Every artist should also be an art journaler!
