Officially bodging PCBs is adding "jumper wires". You'll often use either wire wrap wire (Kynar insulation normally) which you strip normally, or magnet wire which you can strip with a soldering iron. The magnet wire I used was "CNC Tech" part number 610230 (DigiKey
1175-1714-ND).
Adafruit has part number 3522 which should also work. If buying other magnet wire make sure it's NOT high-temperature rated, as high-temp magnet wire won't allow the insulation to break down under solder temperatures. The CNC Tech is rated to 155C for example, you'll often find magnet wire rated at 200C which won't work for this!
