Blueroomelectronics, thank for the reply and great website, I should've discovered those toys 20 years ago.
I see what your saying here, the bimetallic switch interrupts the flow of current when a temperature is reached. However this would not be the preferred method of controlling temperature for this project.
Instead I would like to have to turn only a knob that would adjust what I believe to be the amount of current (I think this would be amps) therefore changing the temperature.
I was looking at using heater wire like this

because this would be used in a type of garment.
This type of wire provides an automatic tripping if the heating element over heats.
