This year at the Seattle and Portland Mini Maker Faires I did a presentation on getting started with designing your own PCB using KiCAD. In this presentation as an example I created a pumpkin shaped PCB with a candle like flickering LED.
Here are the KiCAD schematic and PCB layout files to use as the starting point for your own project:
