Kyle Pasciutti works on a haunted look for Heidi Leger during Tuesday night’s demonstration at the Mattapoisett Library, where the owner of Connecticut-based Decimated Designs turned local faces into living Halloween masks. Michelle Skaar of the library’s young adult programming invited the makeup artist for her teen group, but it quickly became apparent that mask making is a cross-generational activity. Pasciutti decided to pursue makeup when he was a theater art major in college.
