Letters are weather-resistant for outdoor parties but covered areas recommended in case of rain. **Tips From Other Parents** Book at least two weeks ahead for popular weekend dates, especially during school holiday periods. Position the letters where there's good natural light for photos — they work brilliantly as a backdrop for the birthday child's portraits.
