Since I've begun spinning lace weight yarn out and about in public with the drop spindle, I've starting to get a new question from non-spinners: "Does it have to be that thin?"
I say no, it doesn't, and actually this particular yarn won't end up this thin when I'm done plying it. I let the single relax and curl back on itself to show them an idea of the plied size.
They say, "oh," but their eyes look unconvinced. I'm deviating wildly from their expectations about yarn, evidently.
By contrast, talking with spinners, it's all, "How thin can you spin?"
