This design features a graphic with a heartfelt message. At the top, the phrase "Thank you for being my" is written in a cursive font, followed by the word "sister" in a larger, bold font. Below this, the words "UNBIOLOGICAL SISTER" are written in a playful, handwritten style. The phrase "Thank you for being my" is repeated at the bottom of the image, mirroring the sentiment at the top. Adding a touch of sentimentality, there are two diamond emojis on either side of the text, symbolizing love and appreciation. The overall design is simple yet expressive, conveying a strong sense of gratitude and affection.
