A few years back, I used to create quick collage pieces in my daily planner on most days. I used it as a warm-up before I worked on my big art projects.
As I worked on the pieces, I wasn't concerned about composition, color or making the perfect collage art. Instead, I enjoyed the process of cutting and pasting. I used paper scraps (from my current projects), ephemera - as well as words I had cut out from magazines and catalogs.
Recently, I've been making quick collage art in my Hobonichi. I've included a sampling of some of these pages. I blotted out my daily personal jottings with a sheet of paper.
I really enjoy making these collage fragments and many times they give me ideas for larger art work.
