Basic Armouring - A Practical Introduction to Armour Making

Stepping out into the world of medieval combat recreation can, like any other sport, be somewhat daunting. To start with where do you get all the equipment you need, especially all that nice shiny armour? Well here are your options:
1. Borrow it (a good way to start if spare stuff is available)
2. Buy it new (can be expensive)
3. Buy it second hand (cheaper but will it fit or be worn out already?)
4. Make it yourself.
5. Any combination of the above!
