"Cover rocks with mirrors and they look like melted disco balls." I don't think these are rocks but if you could find a "melted" looking rock you could cover it it pieces of mirror or CD's to create a "Melted Disco Ball".
A fun and unique way to give back this holiday season, with a special set of in-store events. You create an ornament in our stores on November 18th and 28th and JOANN will donate $1 to children at St. Jude Children's Research Hospital (up to $50,000). All free to you. Materials as supplies last. To learn more about all in-store events visit: www.joann.com/st-jude #MaketoGive
