Holly Christensen, a former oncology nurse, saw how much joy she could bring to young cancer patients and their families when she made a soft yarn Rapunzel wig for a friend’s daughter undergoing chemotherapy. What began in 2015 as a thoughtful gift has since spun into a national nonprofit, the Magic Yarn Project. Volunteers at 10 chapters across the country turn yarn into character wigs for children with cancer (or any child dealing with medical hair loss). This is reported by correspondent Serena Altschul.
