Perhaps you'd like to see what my Compost piles look like, the ones in the studio, not the big one in the garden. The first photo shows the contents of one of 3 large plastic Compost-to-go boxes, 10" x 14" x 4" boxes with a hinged lid.
The second photo is looking down into one of the large drawers in my work table. You'll notice that there aren't a lot of magazine pages or ephemera in my boxes other than those that somehow relate directly to my life.
Although I once worked with appropriated images torn from whatever books or magazines I came upon I didn't find that to be very satisfying for my more serious work, and I felt that the resulting work could have been done by anyone. So I started preparing my own collage papers and using my own photographs as well as those of family and friends. I do love using ephemera in my travel journals; these bits and pieces of papers collected on location add so much about the place I'm visiting as I work in my journal.
