Create a printable 3:4 portrait Christmas coloring page on a pure white background, using only clean, solid black outlines. Show exactly six equal square panels in a neat two-column by three-row grid, with generous safe margins and a small even gap between panels. Inside each panel, place one large, clear hollow outline numeral at the top and one simple Christmas illustration centered beneath it. Read left to right, top to bottom: panel 1 has the exact numeral “1” and a bell; panel 2 has “2” and a stocking; panel 3 has “3” and a candy cane; panel 4 has “4” and a snowman; panel 5 has “5” and a wrapped gift; panel 6 has “6” and a five-point star. Make every numeral an open, unfilled outline shape with a broad, smooth contour and a spacious white interior, easy to color. Draw each motif in friendly, recognizable, uncomplicated shapes, with closed outlines and a consistent medium-bold line weight. Keep each drawing comfortably inside its own square. Use no extra words, labels, decorations, border flourishes, or objects. No color, gray, shading, hatching, texture, or filled black areas. Leave the interior shapes white and open for coloring; crisp, even, print-friendly line art.
