Can anyone link me to a tutorial that will teach runs between chords? Both ascending and descending?

Or, will someone volunteer to teach our own Josie Cooper? Josie is learning arpeggios as a step toward learning finger picking but I've encouraged her to learn runs between chords in the meanwhile to give her a much fuller guitar sound.

@Danny C, I know that you could tutor her but Jazz/Blues runs are a ho different animal. I want her to first learn Folk, Country, Campfire runs.

I don't recall a tutorial per se anywhere on the web.

It's such an honor to watch this little lady progress while paying "her dues" in full.
