Prepare the paper
Print one pattern at actual size and trim excess white paper around it, leaving enough border to hold it in place. Cut a few small relief slits in the paper margin, stopping well before the design.
These slits let the sheet overlap slightly on a curved surface. If the face is especially round, use several small sections rather than forcing one flat page to lie perfectly.
Place the design
Mark the center of the usable pumpkin face with removable tape. Align the paper center to it, then tape the top, sides, and bottom. Step back and check whether the image looks level from the viewing position.
A tiny adjustment now is easier than correcting every line after transfer. Keep the pumpkin stable on the work surface.
Transfer clearly
A blunt transfer tool can make small marks along the outline through the paper; work in short, regular intervals and connect the marks after removing the page. Another option is tracing paper suited to the surface.
Whichever method you choose, test an inconspicuous spot first. Make key corners and junctions especially clear so you can tell which side of each line is an opening.
Check before cutting
Remove the sheet and compare the marked shape with the printed original. Redraw any missing curve, confirm which areas should remain solid, and simplify narrow points where needed.
Keep the printout nearby as a reference. An adult should handle sharp tools; the digital file is a layout aid, not an assurance that a particular cut will work.
