1 week before the party, here are some party planning tips: A little scurrying around now will save you from headaches the next day or two! Place an order for baked goods. Cakes, cupcakes, and pies should be ordered right away. Some bakeries will need more or less notice depending on your preferences and their schedule, so double-check their ordering instructions ahead of time. Keep in touch. Then, using event planning software, distribute your final guest list to caterers, party assistants, and anyone else involved in the planning process.
