Determine the budget
First of all, you need to decide on the budget you need to allot for the picnic. This can be determined by listing down the number of guests you need to invite. You should include all the supplies and decorations before you prepare a budget so that you can get a clear estimate of things.
Decide on the setting
You must decide whether you need to go for a theme or not. Many people go for different comic themes when they intend to take their kids out for picnic. The setting will be according to the theme. For example, if the picnic has a lot of young ones you would want a lot of balloons and toys in the setting.
Decorate with beach umbrellas
Beach umbrellas would give the picnic a classy look. The umbrellas will also provide shade if the function is in the day. Set the location with as many beach umbrellas as you like depending on the number of guests.
Use citronella candles and plenty of lighting
Citronella candles will also provide a fancy look to the setting and their biggest advantage is that they keep insects away. Insects can be a huge problem considering most picnics are held in open areas where there is great chance of flies and insects disturbing you. You can also set spot lights around the area. A fire in the centre would also be a good idea if the picnic is at night.
Set the area with balloons
You can decorate the place with helium balloons. Different coloured balloons around the area of the picnic setting will give the place a very nice and colourful look.
