Joseph Olsen, an author of children’s books from Cornwall, is giving a portion of his book sales to buy packages of underpants for children in need.

Olsen was homeless as a child and often relied on donations for new underwear and clothes.

"Survivors are resiliently navigating their safety and their children's safety, and to be able to provide a basic need just continues to support them," says Olsen.

The 40-year-old author has also set up collection sites throughout Cornwall for others to donate.

"There are always going to be kids in need," he says.
