Extended Blind Contour

I decided to do this like this because I didn't plan it at all. 

I used oil paint pastels, watercolor, and my collage pieces with ink pen on the collage paper.

I started by making a bunch of blind contour pieces for the collage over the background. I started the background with the oil paint pastels using them to blend the colors. After that I added more to the background with watercolor. After I finished the background I glued the blind contours on top.
