Instructions
You can pre-cut shapes so that the kids can just roll them up and trim, or give them half sheets of felt and let them roll them up themselves and then trim them. If you cut them first, just cut out a fan shape, then roll. Secure the cone shape with hot glue. You can use felt glue, but they will take longer to dry and you will have to hold them closed while they do, thus adding time to the craft.
Trim the bottoms so that your cones stand up by themselves.
Cut out simple eyes and mouths from black felt and use felt glue to adhere them to your ghouls.
Dip the handle end of a paintbrush into white paint and dot on some eyes if you like. You can also use a paint pen. Let dry.
