Material List:
Several wire coat hangers - the stronger the hanger the better they will support the weight of the "Spectres".
Cheese Cloth: There isn't a prescribed amount since it varies upon personal taste and the size of Spectres that you are making. You can't go wrong with several yards of it though!
One container of RIT dye (white): This is what makes the Spectres glow under blacklight. If you don't need your decorations to glow, you can ignore any of the steps that pertain to the RIT dye.
A fake skull: Notice that I specified "fake." This is because it is EXTREMELY difficult to push a coat hanger through a real skull. These fake skulls can be purchase just about anywhere around Halloween. But if you are a real do-it-yourselfer - or you want to make a bunch of these Spectres, you can make your own skulls using my "Cheap Skulls" technique.
