3. Neon Age Signs
Personalize the party by displaying the birthday child’s age in glowing neon lights. Place it on a galaxy-patterned pedestal for maximum impact. If a neon sign is a no go then go for a big metallic balloon number.

Scatter yellow, blue, and pink star-shaped balloons around the ceiling. Draw little eyes on them to turn them into Lumas.
