Decorations for a party in the park or another venue…
Blow up lots of balloons beforehand and anchor them ~ this looks festive and also marks the parameter of your party area.
Streamers would work well in a community center ~ again this could mark off the party parameter. Also, they could be strewn between trees in the park.
If there is a fence around the park, you could decorate it with material, etc. to make the area look festive. If you were doing a safari theme, as an example, you could hang vines off of the fence to give a jungle feel.
Use colorful blankets in the park for the children to sit on ~ also adds festive color.
