Holly Christensen, a former oncology nurse, saw how much joy could be brought to young cancer patients and their families when she made a Rapunzel wig out of soft yarn for a friend's daughter undergoing chemotherapy.

Volunteers at 10 chapters nationwide transform yarn into character wigs for kids with cancer (or any child dealing with medical hair loss). Correspondent Serena Altschul reports.
