Decorations
At the front entrance to the party, bunch blue, white, and green balloons together to create a beach effect.
Buy plastic fish and put them on the fence, hang them in trees, or place them on the party table.
Create jellyfish by attaching blue and green streamers to dinner-sized paper plates with tape. Hang them from your ceiling with fishing line at the front entrance to create a floating jellyfish effect.
Fill the kiddie pool with plastic fish.
Set out colorful beach towels.
Make a giant sun from yellow poster board and tack it up on a tree or the fence.
For your party table, use blue, green, and white tableware to evoke a beach theme. Scatter sand and small shells for confetti, and use a sun Mylar® balloon attached to an oceanic stuffed animal as your table centerpiece.
