A 14-year-old Northport High School freshman is using her sewing skills to keep Long Islanders safe.

Lia Edlin Miller's handmade masks have helped raise thousands of dollars for local charities.

"At the beginning I know it was really hard to find them and people were sending them to hospitals, but I wanted to make sure everyone had access to them," says Miller.

The East Northport teen says she has made nearly 3,600 masks. Each mask is created in her home with patterns ranging from flowers to "Star Wars" characters. They are all washable and reusable.

The teen says she got the idea back in April from a family friend who shared one of her masks on social media.

Since then, the freshman has been working nonstop to fill orders.

Edlin Miller says it takes her around 10 minutes to sew a single face mask, but when orders are rushing in, she can spend six hours a night sewing, stitching and ironing.

All of her sales come strictly from donations -- the masks are free. She asks that people give what they feel comfortable contributing.

She sends all of the money she makes from the donations to local charities, like her high school's food pantry.
