A hat I'd knitted a number of months ago disappeared for a while. It is a gift for a family member and the person's birthday is approaching, so it was becoming more important to find it. I even started knitting a contingency hat.
I finally found the lost hat, at the bottom of a box of yarn. Huzzah.
While I was rummaging in the yarn box, I pulled all the boxes out and organized all the yarn. I sorted by weight and then sorted the fingering weight by content, since that's what I have the most of. Before, the yarn was all just sort of in the order I'd bought stuff. Organizing it was a task I'd had on my to-do list for a while, so I got the satisfaction of checking it off.
I mentioned to someone (someone with a fabric stash) that I'd done this task and she asked if I found any yarn I'd forgotten about. I found just one ball of yarn I'd completely forgotten I had. Such is the power of having filled out a Ravelry stash inventory. As a bonus, the yarn was in a colour I'd been thinking of buying. Electric blue, if you were wondering.
I matched up three more patterns with yarn I have and put them in my Ravelry queue. I think most of the yarn is matched with patterns now. It's just a matter of getting around to actually knitting it up to reduce the amount on hand.
