From the website: “The Christmas-at-Sea program of the Seamen’s Church Institute brings hospitality and love to deep-sea and river mariners with Christmas gifts containing handmade scarves, caps, vests, helmets or socks, as well as other useful items such as stationery kits, sewing kits, magnifying lenses, mirrors, combs, etc. These items are knitted or crocheted by more than 3,500 volunteers across the country. Each year, more than 16,000 gifts are distributed. We would love to have your help.”
