A group of young ballerinas practices their angelic moves at Upstage Downtown Dance Theatre on South Main Street in Celina this week. In observance of National Dance Week, the studio will offer free dance classes on Saturday for anyone interested in learning the art. All age groups are welcome at adjusted times throughout the morning from 9:30 to 11:40 a.m., youngest clients arriving first. Refreshments will be served and a drawing will be held for free summer dance classes.
