I hope Julie doesn't mind me posting some more information (I'm hoping it may inspire of at least suggest some ideas for others).
I thought I should elaborate on my recent post of the three new pieces. I am showing here some detail of the Jackson piece. Each of the pieces shown on the previous post were done on small masonite panels (6" x 6" x 3/8"). This allows me to do some "wrap-around" of the elements from the front surface of the pieces to create additional areas of interest (I hope). I hope these photos will give you a better idea of what the pieces look like. In this particular piece, I really like the way the cut-out portion of the dark green element creates what looks like a little golden cube (BTW, the Golden's iridescent gold paint was purchased for very cheaply at a garage sale!). The dark green element was a serendipitous addition to this piece. I had been doing some "punching out" of that paper to get those oblong little pieces. When I saw what the "negative space" looked like, I envisioned it working with the rest of this piece. Serendipity is one of my favorite parts of collage work. Enjoy!
