Picnic Themed Wedding
Picnic weddings can be as elegant or as casual as you like. You can rent a fancy or modest tent, gazebo or outdoor shelter and decorate it as simple or as elaborate as you wish.
If you want something very plain and simple you can invite you guest to show up in casual dress attire and ask them to bring a covered dish and their own lawn chairs.
If you want something more elegant the dress to the tens and hire a catering company.
