At the moment, I am doing my art journal pages in a simple way. I do the backgrounds first, usually acrylic paint in layers of different colours. These two pages have some homemade stamp backgrounds added at the end. I do a bunch of backgrounds at one time.
Then I put some collage down. Just simple cut-outs of some of the images that I have been keeping. I like to cut a single image out rather than a an entire picture as it becomes more a part of the page.
Finally I have been writing stuff that I want to save out of my morning pages, - usually insights that I think are helpful.
