On each cardboard sheet, draw a large oval or pumpkin segment about 12 inches tall and 10 inches wide. You’ll need 8-10 identical pieces to form the full pumpkin shape.
Use your utility knife to cut along the outlines. Then, glue or tape the edges of each piece together, slightly curving them inward to create a round 3D form.
Once all sections are attached, cover the seams with masking tape for added strength and smoother texture. Don’t worry if it looks patchy, the paint will hide it.
Draw a classic Jack-O’-Lantern face with a marker, then carefully cut out the eyes, nose, and mouth.
Roll a small cardboard strip into a cone or twist it to form a stem. Attach it on top with hot glue and secure it with masking tape.
Paint the body orange and shade the eyes and mouth edges with black for depth. Let it dry completely.
Place LED lights or a small battery candle inside to give it that eerie nighttime glow.
