For a modified version of this project, decorate a large tree limb with the ghosts and pumpkins and then hang the limb over your door. You can also make one or more of the trees in your yard a living ghost and pumpkin tree. There's no limit on how big or small your tree can be!
This craft is easy to make and fun for the kids. However, it does require the use of scissors. Fingers could also come in contact with the sharp edges of the pipe cleaners. Adult supervision is required.
