Fall is a busy time for moving and changing homes. And many people have relocated because of pandemic-related changes in work, school and home life. Over the centuries, traditional housewarming gifts have included bread and salt or wine or honey. Some suggestions from designers for creative, modern housewarming presents include personalized welcome mats, an electronic key locator or a portrait of the house made from a photo. There are cozy options like a throw pillow or candle. Or subscription gift boxes for flowers or decor items. For the kitchen, consider a cutting board, mixer or monogrammed backyard picnic supplies.
