This is four different paintings. The first painting was different lines etc. to represent boundries. It was made using oil paints. The next paper was placed face down on top of the previous to make an imprint of the lines, but showed that they were fading and were not as prevelant. I added more lines or boundries to that sheet and repeated this process until I got the four papers. I then went back and added lines using oil pastels and other paints to show the prevelant and bold boundries could be erased but could clearly and definitely be back.
