I downloaded my Ravelry stash as an Excel spreadsheet, totaled it up, and discovered that I have 24,208 yards of yarn. That equals about 13.75 MILES of yarn.
And that’s not even including my secret Wool-Ease blanket stash. *blink*
Suddenly, my yarn diet successes seem very meager when viewed in perspective of all the MILES I have left! 
Don’t worry, I don’t think there is a stash police or anything.
