How to build an "addon" or shield?

Hi,

I have created a small setup with a potentiometer, some resistors and some LEDs. In order to do some demos with this, I would like to avoid wiring this setup over-and-over, and build a small board that I can plug into the Arduino.

What do I need to take my setup off the breadboard and more into a real "device" form?

Thanks!

Thanks! Indeed the parts I was looking for. I'll try to take a hold of them soon.
