Design a button using the theme We are Evergreen Park. All designs should be turned in to the Children's Services Desk no later than 4 pm on Sunday, March 31. Library staff will select one winner in grades K to 2, 3 to 5, and 6 to 12. The three winning button designs will be turned into buttons that will be available to patrons during National Library week (April 7-13), while supplies last. Entry forms can be picked up at the library.
