"Dear Leo," で始まる、サンタから届く個人向けのクリスマスレターです。北極のレターヘッド入りで、歯医者で勇敢だった子どもを褒めています。クリーム色の紙に紺色の文字と手書きの "Santa." のサインが左揃えで並び、右上に赤い線画の小さなそりがあります。子どもの名前、褒める内容、結びの言葉、署名を差し替えて作り直せます。

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.
