Retro Birthday Waves Card

This design shows an off-white, semi-oval sign centred on the card, edged with a dashed border, like a friendly label set aside for someone special 🎉. Across the middle of the sign, “HAPPY BIRTHDAY” appears in large sans-serif letters, lightly speckled with red, and the text reads as a warm announcement meant to be shared. Above the sign, wavy rays spread outward in golden orange and deep brown, like sunbeams leaning in for a cheerful embrace. The top patterns feel close and inviting, as if the card is reaching towards the reader with an open, affectionate gesture. Below, interlocking waves roll across the bottom in crimson and teal, outlined in black, curling together the way close friends naturally fall into step 🎁. The warm upper tones and cool lower tones balance each other, giving the whole layout a lively, retro look without feeling busy. The dashed border around the central sign stays crisp against the off-white background while the red-and-teal waves pack the lower half with swirling motion.
