PEP ART: Where do artists buy their materials? Barbara McCarren, one of the exhibitors for the new mixed-media show “Imperfect Order,” which opens today at the Irvine Fine Arts Center, says it could be anywhere. She needed 194 magnifying glasses for one of her works at the exhibit. . . . “I just called a novelty store” which sold her 600 for $30, says McCarren. And where did she get 15 decorative Christmas tree-shaped car deodorizers she needed? At Pep Boys, of course.
