I produced a print called Collecting Smiles as part of a Sensory Data Mapping project (more info in earlier Behance post on the project). I decided to run an activity based on my print and smile observations at Brunswick Festival in Brighton. I set up a stall for the day and gave people postcards I'd designed with space on the back for drawing, I asked them to start collecting their own smiles from other festival-goers. It proved to be popular, and most of the postcards came back, filled in, a marker of success! Please scroll down to see workshop instructions, a broader outline of the project and a selection of the postcards that were completed on the day.
