Robert Burridge (Bob Blast) makes energetic, simple you-can-do-this collage exercises. Try this one, demonstrated in under 7 minutes.  It’s splashy, instinctive fun and results in a simple abstract.

Materials used: black and white photocopies, a canvas or board surface, gel medium (used as ‘acrylic’ glue), generous wide brush, a favourite colour of acrylic paint, and white gesso.
