If you're creative or feeling ambitious, you can make your own ghosts,following directions from Sherry Osborne, About.com's Guide to Family Crafts
or others on the web. Or, you can do what I did, and save yourself some time and hassle by just using premade ghosts, like these fairly simple and easy-to-assemble spirits I reviewed
from Grandin Road
. I liked having the ghostly trio all there and ready to go, so I could focus on my flying trickery.
