The easiest way to make a pumpkin costume is to purchase an oversize orange T-shirt. Use felt to cut out the eyes, nose, and mouth of the pumpkin. Apply these with fabric glue directly on the T-shirt. Wear black pants or leotards. Put on the T-shirt, and tuck it in the pants leaving openings so your can stuff the t-shirt with newspapers or other stuffing of your choice. You may need assistance tucking and stuffing as you go. For the stem, use a toilet paper roll and paint it brown. Cut out some green leaves from felt and glue them on the roll. Use a green baseball cap or other hat to mount the stem too. Cut a whole across from each other in the toilet paper roll and attach to the hat with elastic. Wallah you are a pumpkin.
