"Dear Leo," opens a personal Christmas letter from Santa on North Pole letterhead, praising a child for being brave at the dentist. Navy lines and a handwritten "Santa." signature sit left-aligned on cream paper, with a small red outline sleigh at top right. Remake it by swapping the child's name, the achievement praised, the closing line and the signature.

Create a finished, modern minimalist letter from Santa on a portrait 3:4 sheet of clean white paper. Keep all print-critical content well within a generous 8% safe margin. Use a warm, very subtle paper texture, otherwise uncluttered. Set “NORTH POLE” as a small, refined navy letterhead near the top left. Add one small, crisp red sleigh icon near the top right: a simple elegant line drawing, no characters, no extra holiday motifs. Below the letterhead, set the exact letter text in clear, friendly navy humanist sans-serif lettering, large enough for a young child to read easily. Preserve every word, apostrophe, and punctuation mark exactly; use these line breaks for a natural letter rhythm: “Dear Leo, you were brave at the dentist this year. I'm proud of you! See you soon, Santa.” Keep the body left-aligned with generous line spacing and ample space around it. Give “Santa.” a modest handwritten-signature character while keeping it legible and navy. The overall design should feel personal, reassuring, contemporary, and quietly Christmassy. Restrained navy and white with only the small sleigh in muted red. Soft natural light, subtle paper shadow, no border, no extra text, no stamps, no additional names, no watermark.
