That is the current estimate of the number of yards of yarn in my stash. Yes, me--the one who denies having much of a stash at all. And this does not include some of those partial skeins lying around. Whoops
I guess I better get knitting.
To get your own estimate, make sure your stash in Ravelry is updated, then use the export to excel button. From there it is a simple task to sum up the total yards (or meters if you prefer).
Oh crap--I just calculated the number of miles of yarn.
1 yard = 0.000568181818 miles
So I own approximately 22 miles of yarn.
