Our most recent party was simply having cake at the neighborhood park gazebo. It was a hit.
I planned it 6:30 until 9ish when it got dark. The sun was low and the temps were only in the lower 90's. It was also a Monday night in the summer, when no one had school, and the only ones having to get up early are the parents that work. Not having it on a Saturday helped because no one felt rushed or pressured to be somewhere else and prioritize.
I made a cake, using decorating ideas I googled on the internet. It was two round layers side by side. Iced over with white icing. Crumbled up chocolate cookies on top in a figure 8 for a race track. Green sprinkles for grass, and white icing piped around the track for a road effect. We put a Lighting McQueen car on the track. Voila!
We had a cooler full of capri suns, water bottles, and sodas. Everyone just grabbed what they desired to drink with their cake.
Plain colored plates are a buck a package. Had that with a matching 98 cent plastic disposable table cloth, and same price for napkins.
Quite a few families showed up. We just sat there and visited and laughed while the kids played and played.
It was like an old fashioned gathering. Luckily we had a breeze, so it actually felt not hot.
Everyone loved it so much, and non of us wanted to leave. It was low key and low expectations. But it was wonderful.
Plus I didn't have to clean house and plan games and become Hostesszilla!
The party favor bags were just for the children that were the same age as the birthday child. The older ones understood.
That cut down on costs, especially when I found most items in multi packs at Dollar General. (chalk, cowboy and indian figures (like the green army men), playdoh, etc) The only "candy" item was Cars gummy fruit snacks. A box of ten is about a couple of dollars at
Walmart (at the most).
