I don't make clothing but I do crochet animals and plants. I often use it because it's the brand of a particular colour I am looking for and it comes in skeins large enough to need fewer to get a project done. I'd love to use the $22 per 90 yard stuff but it's really out of my budget if I want to sell my final product for under $100, which is what the market seems to allow for plush animals below a certain size. So I go with the $5.99 per 160 yard RH Buttercup and then I can afford to price things so that people actually buy them. I don't use SS because it's not bulky enough for what I'm doing.

I think RH makes some interesting yarns that I think feel nice and soft, like Buttercup (which I often call "baby duck") and Light & Lofty.
