Saying 'a mask' can mean almost anything. Will you paint a paper plate and glue it to your forehead? Do you want a Venecian mask affixed to your glasses? A cocktail or Domino mask either affixed to a hat or to a handle? Do you want to carve a tribal mask weighting 50 pounds? A full Mickey Mouse head that you just happen to misname a mask?
And the ever important: What's your budget?
I'm through with assuming that people want to save money, then finding out their budget is greater than the sticker value of my computer.
Theology is similar to a fortress in the fact that no crack can be accounted small on either of them.
