Sometimes it's fun to watch things get made.
Here is a time lapse of a collage page in my Midori Art Journal - (sorry it's a bit blurry, and maybe too fast to really see much . . . )
I started with the blank pages in my Midori insert made from a calendar, and a Buddhist tapestry. I had some images pre-cut, and others I cut and tear in the video. (Unicycle rider, jellyfishes, artichokes). I glue those things down, add some dots and words and swirls. and there's an outline in Copic marker. I play around with a stamp and fortune cookie fortune, the fortune never finds a place.
Some notes on materials:
I use a tear bar to make straight tears on pictures, and scissors to cut them out, and I also tear with my fingers.
I use spray mount (spraying in a glue box) to make the pictures stick nicely to the paper.
I use copic markers, and a tul black gel pen for the words.
I held the pages flat with large paper clips in the upper corners.
and some composition theory - not thought of while working, it just sort of happens from experience: I used lots of red and green, compliments which make a strong compostion, lots of repeating circles, and a balance of empty and filled space. You can see me moving things around until my eye is pleased with the placement. I find it better not to "figure it out" but just to do what feels and looks good.
and the final page:
"The aim of art is to represent not the outward appearance of things, but their inward significance."
