silk collage art?

Another painting almost finished. I have been wanting to do something different with these silk paintings. I think I have been inspired by all the collage art that I have seen lately. I want to add dimension. My hands ache to sew! I am thinking of adding some stitching...maybe play with chiffon cut and torn, sew on top of the finished piece. What do you think?

Do you like the two tones background?
