The Mokena Community Public Library District is encouraging the community to swap their lightly used costumes to save resources, packaging, transportation costs and money this Halloween season. This event is a free event in which patrons may donate Halloween costumes for all ages during the month of September. On Friday, October 4th from 10:00 a.m. – 5:00 p.m., patrons that donated a costume may come in during the designated time to select costumes from among the donations. All leftover costumes will be donated to charity. Please call 708-479-9663 for additional information on the costume swap.
