I took pictures of the process as I went along (except I forgot one adding the darkest salmon value.)
The piece I created uses the following techniques to create depth:
OVERLAPPING: first layer is text with black ink; second layer is text with gray ink; third layer is light value painted cheesecloth; fourth layer is medium value painted cheesecloth; 5th layer is dark layer painted cheesecloth; 6th layer is needle punched roving using the same textual movement used in the background first layer. I fused the layers moving from the background to the foreground with each layer going darker.
TRANSPARENCY: layers of cheesecloth
SIZE: rectangles smaller and smaller as they come to the foreground
PLACEMENT IN PICTURE WORLD: blue oval is near bottom
COLOR AND VALUE: Both rectangles in different values and pop of blue color
