What decorations do I need?

Every girls’ theme needs the same five items: a balloon garland, a backdrop, a banner, matching tableware and a cake topper. The theme changes the colours and cutouts, not the structure, so the garland and tableware setup can be reused.

How much does a girls’ party cost?

Budget $80–220 for decorations and tableware for 15 children, or $5–15 per child. A balloon garland and backdrop are the main costs; plain tableware in the theme colours keeps the price down.
