My boys like crafts insofar as they enjoy the sensation of squeezing paint through their fingers and seeing how many times they can cover their shirts with stamp prints before I stop them. This project managed to hold Tater's attention for a little while.
craft paint (brown and orange) Tater used washable paint
chenille rods (green)
Fill paper bags with newspaper to create a rounded form. Twist the top to form a stem. Paint the the bag orange on the bottom and the stem brown. Let dry. Tie a green chenille rod around the base of the pumpkin stem for a vine.
You could also make an apple for a back to school project.
