So, now we're into February, here's the count:
Actually, the stash loss would have been more, because in the last couple of weeks, I've made three handbags and a load of little pouches to fit Easter Eggs. A lot of yarn has been used, but there are still some complete balls left, so I couldn't mark it as being Used Up, although I did put some remaining balls up for sale or trade. I also ripped out a cowl I knitted a couple of years ago, so the yarn from that has been added back to the list until I can get it used up. However, I've been behaving and the only new yarn I've bought has been one ball to complete a project. That's been good both for the diet and my credit card bill!
So far, so good. But there's still a long way to go yet :-)
