A deep teal frame with soft, rounded corners surrounds each card in this mermaid set. On the main front, a big lavender clam shell with a single pearl fills the top, a teal mermaid tail flicks out of the upper left corner, and pink coral and green seagrass climb the two sides. The sample reads “Mermaid birthday wishes” for Avery, turning 8.
Two fronts to choose from
The second wording, “Under the sea with Avery,” replaces the clam with a sprig of pink coral, a strand of seaweed and a small shell, so it reads more like an ocean party than a mermaid one. Both wordings come at 5 x 7 in, 7 x 5 in, 4 x 6 in and 6 x 4 in, and every one of those has a photo version with a rounded box above the title for your child’s picture. On the landscape cards the mermaid tail moves down to the bottom edge.
The party trail card
“Follow the party trail” is a 5 x 7 in card with four numbered stops (a pearl welcome table, a shell craft cove, ocean treats and the birthday treasure), plus a rain plan, the time, the address and a reminder to bring a light jacket. Change the stops to whatever you have planned.
The rest of the set
- An invitation back, “The party details,” at all four sizes
- A 3.5 x 5 in “Join the celebration” reply card asking for name, guests and dietary needs
- A thank-you card that folds to 4.25 x 5.5 in, signed “With love, Avery,” with “A happy memory” printed inside
- A 6.5 x 6.5 in envelope liner tiled with pearl shells
- A tall phone-shaped invitation page, plus the two ready JPGs
In Spanish, the fronts become “Un cumpleaños de sirenas” and “Bajo el mar con Avery,” and the trail card turns into “Sigue la ruta de la fiesta.”
Editing and printing
The template link in the access PDF opens a Canva copy where you can switch the name, age, date and photo. Print the Letter or A4 file at 100% and cut along the crop marks; most cards print two to a sheet, and the color runs a little past the cut line so the edges stay sea green.
