For our district-wide annual String Fest, we hire movers to transport chair and stand racks as well as cello and bass racks from the elementary schools to the high school's field house. We want everything to end up racked up properly and returned to the proper school afterwards, so we are careful to label everything clearly. I like to color code everything by school and add a picture of the school's mascot too. I laminate the labels and then just use masking tape to affix to both the back and front of racks.
