Block Printing on the Green Collage

I am showing the process I used to make this piece, which will be debuting on Friday, August 24th at the Pacific Northwest Quilt Festival in Tacoma. 

I've already shown the foundation of dyed fabric collage, then the stitching, followed by the screenprinted moon and hand painted creek.  Now, you can see the block printing.  I used a mixture of white and copper fabric paints.  I am trying to create the feeling of a hazy creek bottom or filtered light from the glow of the moon.
