How can I make a Greek Sword and Shield Please Include Materials and Price

For the cheap version of a shield, use a trashcan lid and cover the top half with aluminum foil. Then you can tape down the aluminum foil if you want. And then you paper mache the aluminum foil part. Then let that dry, and then take the aluminum part off of the trashcan lid and paper mache the part that you didn't cover yet. Then just make handles out of leather or paper mache or whatever and then you can paint it if you want (it would look better).
Here is the link to the expensive way http://www.ehow.com/how4577861greek-shield.html
That could cost around $500 though.
For a sword I would just recommend buying that. Its kinda hard to make one of those. The cheapest one is one of those 300 replica things for like $10.
