Summer Party FAQ

Q: How do I keep bugs away from the food?
A: Use mesh food covers and place a few lavender or citronella candles around the perimeter. Also, keeping a small electric fan blowing across the food table works wonders!

Q: What’s the best time to start a summer outdoor party?
A: I always suggest starting around 4:00 PM. This avoids the harshest midday heat but gives you plenty of golden hour light for photos before the sun goes down.

Q: How do I handle a sudden summer rain shower?
A: Always have a ‘Plan B’ space cleared inside, or rent a quick-setup canopy. Most summer rain is short-lived, so use it as a ‘snack break’ inside until the sun peeks out again!
