Step 1: Stuff you'll need
some paracord (or other strong cord)
dowel that you can get your hand around nicely
AND a drill / drill press (not in picture)
Step 2: Sizing up the dowel
Step 3: The finger cord
with that out of the way, you now have to mark out two dots in the center of the dowel, about middle finger width apart, maybe wider. now, using the drill / drill press, drill two holes all the way through the dowel where you marked the dots.
