I love silk and silky fabrics—but I coarse wool doesn't bother me—my mother sometimes cringed at the sight of me in some coarse wool sweater—worn next to my skin—she sometimes demand I put on a shirt beneath it—It bothered her just looking at me wearing a sweater she found itchy! (I ended up with a good number of sweaters that failed to meet other family members standards for comfort this way—including one an Aunt in Ireland knit!)
As I mentioned, my puffy striped socks (now past the 6 inch inch mark for the foot) are being knit from Kroy sock yarn. My stash is top heavy with Kroy--(a few years ago, as many solid colors were discontinued, I snatched them up—and I liked the yarn so much, I've bought more when ever I can—so I have a bunch of discontinued solid colors, and some odd balls--that look like matches, but are different dye lots (and I am not so picky—when the price is right--at least 1 ball (orange) was $0.50--and anything under $1 is always a good price!)
Some knitters (ones who haven't been blessed with peasant feet) complain that Kroy isn't soft enough (it's not, I'll admit, the softest yarn—but it does get softer with washing and wearing, and it wears like iron!)
While conceding it's not the softest sock yarn -- it's plenty soft for me. But then there is the black.. I don't knit a lot of black--(1 pair (years and years ago now) for my son, and sometimes, toes and heels in solid black, and 3 or so years ago, the ring of fire socks—which were mostly black)--3 examples in a whole bunch of sock knitting! As I knit the foot, I am reminded, of all the Kroy yarns I have knit with, the black is the softest.
It so soft, it is noticeable different. It is distictly softer that the white, or greys. The yarn feels thicker, plusher, too. (the fabric is both softer, and denser) If every color/pattern/style of Kroy yarn felt as good as the black does, Kroy would easily be considered a premium yarn.
I know that different dyes can effect yarns, some leave them softer, some scratchier, but this black yarn is—so soft and plushy—it more than makes up for the difficulty knitting with a color that eats up light like a black whole!
