Artist Amy Stacey Curtis rearranges shoe lasts Wednesday morning on the interactive art piece she created at Museum L-A in Lewiston. Visitors are encouraged to create patterns using the pieces that museum volunteers painted using some of the thousands of lasts in the museum’s collection that were once used in local mills to make shoes. It is part of the museum’s latest gallery exhibit, “The Industrial Heart: Enterprise-Innovation-Creativity.” For information on gallery hours, visit museumla.org.
