I have a small closet that's full to the brim, I have to carefully restack things when I go in there now. I've a dresser that's 3 drawers dedicated just to my Knit Picks yarn. I've handspun sitting on top of the boyfriend's bookshelf, and 5 WIPs on my desk.
Then I made the mistake of using the Excel function of Ravelry's stash page to see just how much I had (that was put into Ravelry).
Just under 30 kg. That's 66 pounds. Once I separated out the Knit Picks yarn (because I knew I had a fair bit), after including the birthday yarn once it arrived, that came to 6.18 kg, or 13.6 pounds. My sock yarn total is 15.9 kg/35 pounds.
So, I decided that instead of picking a set time, like a year, that most people seemed to do, since my main goal is to
One kilogram of Knit Picks yarn, and one kilogram of anything else. We'll see how long that takes me.
