This picture was in the last post-
You may have been wondering, "What's the glue for?". I think I called it glue, and it is commonly used as a glue,
but actually, it's rubber cement. And I use it as a masking agent. It works like this:
1. I apply the rubber cement over the area I want to protect.
2. Let dry.
3. Then I apply as much paint and as many washes as I want. The rubber cemented area resists the paint so it creates a hard edge where the two meet. Also notice how the paint beads up when stroked across the rubber cement.
4. After the painting is completely dry, I remove the rubber cement with this tool oh-so-cleverly called a "rubber cement pick-up". You just drag it across the page and it cleanly pulls up the rubber cement. If you enjoyed peeling dried Elmer's glue from your fingers in elementary school (like I did, please tell me I'm not the only one) then you'd really like this part.
5. Sometimes I leave all the hard edges but in this painting I went back and softened most of them using a clean, wet brush. I also added one final, tiny splattering.
