<< cardboard tubes that come in
How about a relief project that cuts the tubes to different lengths and stand
them on end. Or cut them at diagonals, glue them to an illustration board
and air brush with gesso to make a ground and then with colors, to accent
using the angle of the spray.
I have done assemblages with Styrofoam pieces and Matt board scraps that were
applied at different angles and depths and kept them white on white and then
use available room light to create different shadows on the piece.
