Linda: Another good idea. Some questions: What type of chalk did you use? Was it a chalk dust, a school blackboard stick of chalk, or some other type. Was it white chalk or another color? Was it applied into crevices or did the crevices, without chalk, reveal the print? Might the chalk dust be brushed or washed off?
