First things first, you’ll need to let your guests know about the big day. Mermaid-themed invitations are a must, and you can choose between printed and digital options. Printed invites are a cute keepsake and can be stuck on the fridge as a reminder. If you’re short on time (or budget), digital invitations are quick and easy to send.

Here are some ideas:

• Splashy Mermaid Tail Design: Customize with your party details and print or send digitally.
• Ariel-Inspired Invites: Perfect for those who love The Little Mermaid—customize the text, font, and colors.
• DIY Seashell Invitations: Grab some teal and purple paper, cut into seashell shapes, and add a bit of glitter for a personal touch.

No mermaid party is complete without the right decorations. You can go all out with a fully-themed setup or keep it simple with a few key pieces. Either way, your guests will feel like they’ve stepped into an underwater wonderland.

Here’s how to set the scene:

• Ocean Backdrop: Use a mermaid scales backdrop for photos, or hang light blue fabric to create an oceanic vibe.
• Themed Dessert Table: A tablecloth with gold mermaid scales sets the perfect stage for all your party treats.
• Shimmery Balloons: Ombre balloons in pink, blue, and purple add a touch of magic. For extra wow-factor, consider a DIY balloon garland.

Mermaid Cakes: You don’t need to be a professional baker to create a mermaid cake. A simple cake can be transformed with a few easy tricks:

• Scale Design: Frost the cake with one-inch dots of icing in shades of blue and purple, then drag a spatula through the dots to create a scale effect.
• Confetti Cake: If piping isn’t your thing, go for a colorful confetti cake with pink, purple, or teal frosting to match the theme.
