This is the planning advice I liked the most. Display D-I-Y centerpieces. You can save money on party decorations by creating your own centerpieces using things you already own or can buy at low cost. For example, seasonal fruit is a fantastic way to create a budget-friendly centerpiece: It’s festive, it looks nice, it’s generally inexpensive, and you can reuse it after the party (by eating or cooking with it!).
