"Santa is watching, so be good!" は、温かみのある絵本風イラストのクリスマス・リマインダーポスターです。緑の影が付いた濃い赤の丸文字の下に、雪の積もった木の窓からチェックリストの巻物を持ってのぞく笑顔のサンタがいて、クリーム色の背景に松の枝が添えられています。見出しと下の小さな一行を差し替えて、オリジナルのホリデーリマインダー、挨拶、教室のサインを作れます。

Create a finished square Christmas quote graphic for a children’s playroom. Use a cheerful storybook illustration style with crisp, friendly shapes, tactile paper texture, and bright candy-like colors. Keep a warm pale-cream background, framed by a few simple evergreen sprigs and tiny gold stars; avoid clutter and leave generous breathing room around the lettering. The exact hero text is “Santa is watching, so be good!” Set it in two lines, breaking after “watching,”. Make it large, instantly readable at phone-thumbnail size, and center it in the upper half. Use rounded, chunky hand-drawn lettering with open counters, soft corners, sturdy strokes, and a slight playful bounce. Fill the letters deep cranberry red with a clean cream highlight and a subtle forest-green offset shadow; keep every letter crisp and correctly spelled. Directly beneath the quote, set the exact small supporting line “A CHRISTMAS REMINDER” in compact, widely spaced dark-green uppercase letters. This is a descriptive label, not an attribution. In the lower half, show a joyful cartoon Santa peeking through a small, warmly glowing wooden window, holding a long Christmas list. Santa has a rosy face, bright eyes, a fluffy white beard and a classic red hat; the list has simple check marks and blank lines only, with no readable words. Give the window a few evergreen sprigs and a tiny gold star as restrained accents. Make Santa and the window a clear secondary focal illustration, not a busy backdrop behind the quote. Keep all text and key illustration details comfortably inside the square’s safe margins. No extra words, lettering, watermark, or signature.
