What is the best time for an outdoor summer party?
I always recommend starting about two hours before sunset. This is the ‘Golden Hour’ where the light is soft and flattering, and the temperature starts to drop into a comfortable range.

How do I handle unwanted bugs?
Keep things gentle! Citronella candles and oscillating fans are great ways to keep mosquitoes at bay without using harsh chemicals near the food.

What should I do if it rains?
Always have a ‘Plan B’ heart ready! Whether it’s a nearby indoor space or a sturdy tent, having a backup ensures you can keep the joy alive regardless of the clouds.

How do I keep food safe in the heat?
