Blow up several small balloons. Coat them in papier-mâché
, and allow them to dry and harden over night. Leave a hole where your balloons are knotted, so you can pop the balloons and remove them after your gourds have hardened. Paint your gourds in orange, yellow, green, and other colors. Make stems and leaves out of felt, and glue them over the hole where you removed the balloon.
