Thanksgiving party decorations dress the table and room in autumn colours, from warm oranges and browns to leaves, pumpkins and "give thanks" signs. Set a welcoming table for the meal, then add a few hanging pieces around the room. They're part of our wider party decorations, and the full Thanksgiving party supplies range covers the tableware. A low autumn centrepiece works best, as Thanksgiving is a sit-down meal and guests need to see across the table. For more ideas, borrow from our table decorations too.
