Luna, a receptionist in Lenox Hill Hospital's radiology department in New York City, started the Madresita Project for volunteers to hand-knit hats for chemotherapy patients. The program is in honor of Luna's late mother, who died from pancreatic cancer.
Madresita is an affectionate term for mother in Spanish.
They donated dozens of hats this week for Christmas.
"This is a small token I would like to give back to the patients and their caregivers and, hopefully, bring a smile to their face," Luna says on the printout that comes with each hat she gives away.
