Stack two pieces of orange construction paper then fold them in half. Cut out half pumpkin shapes on the folded edge.
Continue to cut until you have at least 4 half pumpkin shapes. Once unfolded these shapes should look like full pumpkins.
Apply glue from a glue stick to the back of one of the folded pumpkin shapes so it covers one half of the pumpkin shape. Place another folded pumpkin piece on top of the glued side, matching up the folds.
Keep gluing paper pumpkin pieces together until you've glued together 3 to 4 paper pumpkin shapes and the pumpkin fans out around the fold.
Use glue from a glue stick to attach the bottom of the 3D paperpumpkin to the final piece of construction paper. If you're making a greeting card, fold the sheet of construction paper in half before gluing on the pumpkins.
Cut a 1 inch piece of brown pipe cleaner and a 2 inch piece of green pipe cleaner. These will be the stem and the vine. Wrap the green pipe cleaner around a pencil a few times to make it into a spiral.
Use a glue gun to attach the brown pipe cleaner piece as the pumpkin's stem and the spiral green pipe cleaner vine.
Repeat these steps to make 3 or 4 additional pumpkins to add to your 3D pumpkin craft.
