I wanted a really traditional "birthday" theme for DS's 1st Birthday so for decorations I got a bunting/flag banner, made pinwheels for centerpieces, used sheets from the thrift store for tablecloths, and got some balloons.
The bunting and crown from etsy were his birthday gift from us
For food I got a sandwich tray made at the co-op deli and asked each of DS's many grandmas to each bring a side (fruit salad, potato salad, 3 bean salad, etc.) I made cupcakes and decorated them like lions because DS is a leo. And we had a bloody mary bar, and lemonade to drink.
It was such a fun party and turned out exactly how I wanted

There was probably about 30 adults and 5 kids.
