I have a 9x12 sketchbook I used for the dynamic drawing class. Most of the sketches of the tai chi master are not keepers, so I am reusing some of the pages. I applied collage pieces and absorbent ground. I then sketched a house - did not like the result. I applied another layer of absorbent ground, collaged a piece of Chinese print and drew tulips.
I applied fixative between layers of paint because the watercolor lifts off the medium. I also applied metallic watercolors.
