I've had this Brown Sheep Cotton Fine cone in my stash since...2007 or 8. It was part of a Patternworks sale that seemed like a good idea at the time, because I was convinced of my wool allergy (which turns out to be an issue solely with lower-micron wool - pretty much anything that comes from Peru makes me itch just looking at it) and thought cotton was the only alternative (this was before I learned about Amy Singer's No Sheep for You). Clearly, as it has been languishing in the stash since 2007, it was not such a great idea. Four cones of lace-weight, unmercerized cotton might be perfect for weaving, but it's not as awesome for knitting.
But finally, as part of the great stash-busting event of 2013, I took some time to match these cones with projects, and found the Pickle's Plain Cardigan pattern.
I made the smallest size, and even with the yarn held tripled I still didn't manage to use up the whole cone. The only changes I would make if I knit this again is to make fewer button-holes, and to make them smaller. They sort of overwhelm this small garment, and it makes it difficult to find appropriate buttons. I'm still searching - I think dark brown wooden or faux leather would look nice, but I haven't found anything I'm completely sold on yet.
Overall, the yarn turned out to be much more pleasant to work with than I was expecting, and produced a fabric with much more drape than the feel of the cotton on the cone led me to expect that I would get. For my first major Knit the Queue project of the year, I think it turned out quite nicely. And it worked up in a single weekend, so I definitely can't complain about that.
