Tried searching this "two finger method" for honing on google.... ended up back at this post!

Wrap a piece of 220 wet/dry sandpaper around two of your favorite fish-cleaning fingers.
Don't let your girlfriend/wife watch otherwise she'll keep you up all night.
Cross-hatch the bore with your home-made hone, keep everything moving with ample doses of WD-40.
Repeat with 400 wet/dry
Clean with brake fluid, stand back and admire your as-new cylinder.
