A vibrant flat vector illustration featuring the text 'FIRST GRADE' in large, decorative bubble letters. Each letter is filled with different cheerful patterns - polka dots, stripes, stars, hearts, and geometric shapes in bright colors like pink, blue, yellow, green, and purple. The letters have thick black outlines and are adorned with small decorative elements like stars, flowers, bows, and sparkles scattered around them. The 'S' features rainbow polka dots, the 'E' has pink hearts, the 'C' shows teal checkerboard pattern, and so on. Small magical elements like shooting stars and tiny flowers float around the text. The design uses the same playful, colorful patterned letter style as the reference with bold outlines and whimsical decorative accents. The design is print-ready, fully isolated on a white background with no shadows or textures, fully contained within canvas boundaries with no cut-off elements and proper margins around all elements, and intended for use in t-shirt printing. | PODspy AI Design
