From 10 a.m. to 5 p.m., this Sunday at the Hoco Family Arts Festival in downtown Tucson, Bookmans hosts recycled instrument making and Music Hour with Nature. We need your help to pull off this event in sustainable style. Please bring your used paper towel roles, empty water bottles, or clean coffee cans to any Tucson Bookmans location. We'll use them to create fabulous, functional musical instruments to delight children of all ages. We'll follow up our instrument making with a special musical performance with Nature at 2 p.m. on the Club Congress stage, so after you round up recylcables for Bookmans, plan to bring your children to the Hoco Family Arts Festival.
