The word ลอย /loi/ means ‘to float’ and Krathong กระทง /grà-tong/ is a small lotus-shaped floating receptacle.It could be made from anything; traditionally it is made of banana leaves and banana trunks. Today the banana trunk core is sometimes replaced by styrofoam, paper, ice-cream cones, bread (baked into the form of a traditional krathong or a cute floating turtle). The banana trunk and bread krathongs are obviously eco-friendly, so better choices for you and your family.
