A natural disaster inspired Mary Marzano, a woman from Maplewood, New Jersey, to reach out and help others, but after the relief efforts ended, her efforts continued.

When Mary found out from a friend that many hotels throw away gently used pillows, blankets and sheets, she took action. Mary began shipping out these sheets to places in need, including homeless shelters with little to no bedding.

So far, she says she's personally delivered enough comfortable covers for more than 8,000 beds. To help out, all 340 members of Oprah's audience brought along a set of sheets to donate to Mary's organization, Green Recoverings.
