Good Lord... you're kidding?
It's not just bad practice, it's also against the electrical code and a potential
Landmine for the next guy...
Electricity is not something to be creative with. Learn the rules and do it right!

Now that's a different approach. So when you open the box, the bare wire will always be hot. And anything it touches will be hot. Please rethink your solution.

No!
If your area is using the 2008 or lower edition of the NEC, you will need #14/3 w/ground for three way switches.
If your area has adopted the 2011 of the NEC, you will need #14/4 with ground. The 2011 edition requires that you have a grounded conductor (Neutral) at the switch outlet, in case you might want to use a specialty switch.
Black, would go to the common post. Red and Blue (re-tasked as Red) would be the travelers. White (capped off) would be the required Neutral.

Rich,
Do not use 14/2! At a minimum use 14/3. Using 14/2 will cause wiring problems.
The price for 14/3 is pretty close to 14/2. However, personally, I would use 14/4.
The trade off in ease of installation is worth the few dollars difference over 14/2.

I don't know in your area, but Home depot near me will sell any size wire any length. They cut it off a large roll.
