My no-sew adult sized tutu for The Color Run in a few weeks is done!!! Here's how I did it: Elastic cut slightly larger than my waist. Wrap elastic around a chair back and safety pin. Used 4 spools of tulle (I think each spool is 20yds) and cut 20" strips. Loop knotted each strip around the elastic. Hand stitch, pin or knot the ends of elastic together to fit. DONE!
