As is my wont, I went through my entire yarn stash this past week, so that I'd have a full-sense memory of how much and what kinds of yarn I already have. Any, for the first time in a long time, I made an "unhappy pile," as described in the slow stashing manifesto.
In the unhappy pile go all the yarns that immediately cause your spirits to sag. These yarns appealed to your sense of “should”—I should buy this, I should knit something out of this, and, even now, I should keep this. As soon as you find yourself muttering the word “should,” put that yarn in the unhappy pile. Also in the unhappy pile go yarns that, through no fault of their own, carry emotional baggage. Yarns were innocent bystanders to tough times in your life. Yarns that you've already tried to use a few times but always ended up frogging. Yarns that you feel you should use even though the spark just isn't there. Those yarns need to go.
Even now, some of the yarns still call to me. The cotton chenille: wouldn't that make a cool throw with multicolored mitred squares? And the heavy cotton coned yarn: I could knit a quick bulky pullover. But I still have thoughts like that about my knitting machine, and I can move on.
I'd be happiest if I could manage to sell these, although the fact that so many of them are unlabeled coned yarns might make this less likely. I'll give it a go, and we'll see what happens.
