Looking for low-cost sustainable gifts this holiday season? Consider giving the gift of your time and expertise! Volunteer at your gift recipient’s favorite charity. Offer to babysit for new parents. Help with painting or household chores. Or make a home-cooked meal each month for a year. Does someone on your gift list need a running buddy or trainer? Want to learn guitar? Or how to knit? Or a second language? Pass your skills on as a gift. These meaningful gifts are low-impact on the planet and your wallet. However you celebrate, happy holidays!
