Frequently Asked Questions
Q: What if it rains on my outdoor party date?
A: Always have a “Plan B” cozy indoor space ready! Most of these ideas, like the movie night or the ice cream bar, can be easily moved into a living room for a snug, indoor version of the fun.
Q: How can I keep bugs away from the food?
A: I love using mesh food covers—they look quite elegant and do a wonderful job. Also, keeping a few citronella candles around the perimeter helps create a bug-free zone without harsh chemicals.
Q: How far in advance should I start setting up?
A: For summer parties, I recommend doing the “dry” setup (decor, tables, chairs) in the morning and saving the “wet” or “cold” items (water features, ice cream, fresh flowers) for about 30 minutes before guests arrive so they stay fresh in the heat.
