Still Life, Black and White

This black and white drawing was introduced with this still life on the right.

They started with the object; either a cat or a vase on the table.

The cat is with the torn paper technique and vase used stickers and pastels. 

While the object dryed, they draw the table using black pastel only.

The gray was done by rubbing cooking oil with q-tip on the pastels lines.

On the drawing they added water down gauche, either red or yellow before gluing the object on or below the table.
