Cut the PCB Down to SizeMake sure to cut all the way through copper layer. Otherwise it'll tear when the fiberglass snaps.
Clean up the Copper and Lay Out the Parts
Draw Pads and Connect the Dots
Fill in the Ground PlaneIt's easier on your etching (and sometimes has beneficial electrical properties) if you keep a fair amount of copper on the board to use as a very-low-impedance ground path.
Let the Ink Dry, Inspect, Do Small Touch-ups
EtchEtch the board using the etchant of your choice.
Acetone pwns sharpie! Also note that I'm not doing this directly on my countertop. Sharpie and acetone bleeds through paper towels.
