Dress up your guests as Fido or Fifi with these easy-to-make masks. Create a color photocopy of your favorite photo of your dog or cat, enlarging it as needed. Or, for a more human touch, copy photos of friends and family members. Cut out the face; mount it onto cardboard with spray adhesive. Cut around the face with a utility knife. Paint a thin dowel in a color of your choice; when the paint dries, hot-glue the dowel to the back of the mask using a narrow strip of cardboard. Make small slits in the mask to see through. Anchor the dowels of several masks in a basket of wrapped candies, and keep it by the front door; guests can take one as they enter.
