Make waves on their special day with this personalised mermaid birthday card, featuring a charming hand-drawn illustration of a smiling mermaid holding a beautifully decorated birthday cake beneath the sea. Created digitally on my tablet using an ink pen brush, this design blends soft ocean tones with clean line detailing for a modern, whimsical finish.
 
The front reads:
“Happy [Age] Birthday [Name]”
 
Both the age and name are fully customisable, and the hair colour can also be personalised to resemble the birthday girl — creating a truly unique and thoughtful keepsake. Perfect for daughters, granddaughters, nieces, goddaughters, or any little mermaid who loves magical under-the-sea adventures.
 
Printed on luxury 300gsm textured watercolour cardstock, this A6 greeting card has a premium, sturdy feel with a beautiful artistic texture that enhances the illustrated design.
