Create a single printable pumpkin-carving stencil, portrait 3:4, shown flat and straight-on. Pure white background (#FFFFFF) and pure black cut-away shapes (#000000) only: no gray, color, gradients, outlines, shading, texture, shadows, pumpkin, scene, or frame. Center one large, unmistakable uppercase “M” in bold stencil lettering. Give it broad, squared strokes and open, clearly readable structure. Treat black as material to cut away and white as the pumpkin that remains. Connect every white counter inside the M to the surrounding white with broad, sturdy white bridges through the black strokes; use clean, deliberate stencil gaps, not thin hairlines. Surround the M with a circular ring of eight simple solid-black bat silhouettes, evenly spaced and oriented along the circle. Keep bat shapes bold and medium-detail, with no eyes, tiny marks, or enclosed white islands. Keep generous white margins; make the centered design occupy about 70% of the page. Crisp, high-contrast stencil artwork with carveable shapes and bridges wide enough to survive cutting. Render only the letter “M”; no other text.
