Three sea friends carry this under the sea birthday invitation. Along the bottom of a pale aqua card, a blue whale with a wide smile, a round pink octopus and a green sea turtle with a checked shell rest on a sandy seafloor, framed by orange coral and two tall strands of kelp. The upper half stays open water with a few drifting bubbles and the script line “An ocean of birthday fun,” followed by “Avery turns 6” and the party details.

Sizes and the photo version

You get the front at 5 x 7 in and 4 x 6 in, each in portrait and landscape. On the landscape cards the animals move to one side and stack along the edge. Every size also has a photo version with a small rounded “Photo” box between the title and the name, so the sea scene stays as large as on the plain card.

A back with room for a map

“The happy details” back, in portrait and landscape, has a line for snacks and games and an empty box marked “Map” where you can add a venue map or directions before printing.

Reply, thank-you and liner

  • “Count me in!”, a 3.5 x 5 in reply card asking for name, guests and dietary needs
  • A thank-you card printed as an 8.5 x 5.5 in spread that folds to 4.25 x 5.5 in, with “Thank you” outside and “You made it special” inside
  • A 6.5 x 6.5 in envelope liner with wavy lines over the same three animals
  • A tall phone-sized invitation page you can edit, plus two ready JPGs

The Spanish pieces read “Un mar de diversión,” “Los detalles,” “¡Cuenta conmigo!” and “Gracias.”

Personalizing

Change the name, age, date, venue and RSVP contact in your own copy of the template from the access PDF. Print the Letter or A4 layout at 100% without fit-to-page, then trim at the crop marks.
