When I knit something new, I'm thrilled when I use yarn from my stash, but I almost never show pictures of my yarn stash. Why? Because it forces me to see that that I have too much yarn (as if there's such a thing). On the other side, I find it motivating. When it's together in one place, it forces me to better organize it and plan future projects.
How much do you have in your yarn stash?
