Rubbings and Water Soluble

I've cut some shell shapes from cereal packets and used them as rubbing plates in my sketchbook. The blue and green examples were rubbed with Inktense and then some of the colour activated with water to make a paint. I like to combine painted and rubbed areas in the one motif. I then cut out the shapes so those on pages behind can be seen.

The page above is on tracing paper. The page lying below it was washed and covered with cling-wrap whilst wet to give it a nice texture. The shells were rubbed with Inktense on the tracing paper and then parts were activated with water to give more intense colour.

This ammonite was worked in water-soluble graphite.
