Someone on Ravelry posted a link to a yard to miles converter. I exported my stash page to Excel, totaled the yarns column, entered into that converter an learned that I have 12.2454 miles of yarn, or 12 miles and 432 yards of yarn. I thought that was a lot until I noticed that everyone else who had replied had more than me and one woman has 72 miles! Yikes!
In any case, I think I have hit a limit. That stash calculation isn't actually everything I have. There are things in my bins that I haven't put into Ravelry yet. Not a lot, but they are there. I know that I am way behind but I am going to declare that I can only knit from my stash for the rest of the year. When January rolls around I think I will allow myself a purchase or two and then reevaluate. I keep buying sweater quantities of yarn and not finishing the sweaters in question! Unacceptable. The stash is also spreading around the living room. Ideally I will be able to fit it somewhere in the office, once the grand reorganization is done, but for now it has to be in the living room and I would prefer it if it didn't take over.
We'll see if I can stick to my resolution. Wish me luck.
