I know some people love to knit with this and some wouldn't touch it with a ten-foot pole. Personally, I love it. I knit my mom a pair of socks with it last year and thought it was awesome to work with. For those of you who love it, there's a rumor going around that I thought I should share (perhaps it is a clever marketing ploy):
The rumor is that because of the scarcity of enough superwash merino to mill Supersock, once Superworsted is sold out it will never be milled again.
I got this from an email from Trash and Treasure, who is selling it on eBay and their online store (still trying to figure out if that's the same thing for them). I like these guys, good prices, good yarn. One proviso is that they sell mill ends, seconds, endlots, and discontinued colors. I think they have fixed price yarn on ebay also. Their other info says: "This washable yarn is soft and great for socks and sweaters, hats, mittens, scarves--anything you want to be able to wash and wear in a natural fiber. This yarn comes 4 oz/ 215 yards for $20 retail. Buy it before it's gone for $15 per hank."
