“One-der the Sea” Vellum Mermaid First Birthday Vellum Invitations

Celebrate your little mermaid’s first birthday with our “One-der the Sea” Vellum Mermaid Invitation! Printed on delicate 5″×7″ vellum paper, this invite features a sweet teal-and-coral mermaid surrounded by coral, shells, and starfish. The translucent vellum overlay allows the whimsical “One-der the Sea!” headline and elegant script details—name, date, time, and location—to appear as if floating over a soft sandy-gray background. Each invitation includes a matching envelope, making it an enchanting keepsake for an unforgettable under-the-sea celebration.
