I went to a life drawing session tonight, and dragged more supplies with me.  I wanted to try out the oil pastel resist idea.  I found the model very uninspiring and I think the drawings reflect that.  I did have a great time playing with a new combination of materials.  I am liking working with the oil pastels.  I have about 3 sets of very cheap oil pastels.  I decided to use them up before purchasing some quality ones.  They aren't very creamy, to say the least, but they do act as a decent resist.  I posted my favorite first but the correct order starts with the second image.  I put down a red pastel line, then went back with a black ink brush pen.  After that I used some ink washes.
The second painting I decided to use two different colors of resist, then the ink brush pen.  Lastly I added a little blue color along with the ink wash.
Next I decided to put a wet wash of color on the page, let it dry and then did  the brush pen and ink.  Lastly I added the pastel.  I wasn't thrilled with this order of applying the pastel.  
Next, several drawings with different colors of pastel over a washed background, then ink, then I painted stronger color over the body.  Starting to get somewhere here.  
The next idea was to strengthen the color around the body...that is my favorite.
Then I decided to strengthen the color on the body and the outside areas, leaving light forms around the edge of the figure.
The last idea I played with was to use all light pastel lines.  I think I like the more contrasting lines better.
Most of the lines were multiple blind contour drawings of the same pose.
