This greeting card features the words “happy birthday” as the main focus, set in creamy white lettering with rounded edges across the center. Behind the phrase sits a soft, cloud-like teal shape that looks like it’s floating, giving the message a gentle, friendly lift 🎉. The background is filled with vertical, wavy stripes that flow from top to bottom, mixing deep teal, mustard yellow, muted coral, and sage green in a retro-style palette. A light grainy texture overlays the whole design, like a well-kept print that’s been passed between close friends over time. Subtle shading beneath the white letters adds depth, making the text feel slightly raised from the teal shape. The layout keeps the greeting centered and easy to read, while the surrounding waves create movement that feels like a shared celebration 🎂. The teal shape sits over the undulating stripes, with the creamy white “happy birthday” text placed squarely in the middle.
