Last November, I stated knitting series of swatches in the same yarn and stitch pattern but in with different sized needles. For example, I would knit Lion Brand wool in the same stitch on USA size 1, 3, 5, & 7 needles. then every time I was talking to someone, I would pull the swatches out and ask them what they thought of the various swatches. Thinner yarns such, as Paton's classic got swatched on 0, 2, 4, & 6.
The results have been surprisingly consistent. When shown a series, worsted weight yarns knit on 6, 7 & 8 needles are described as too loose or flimsy. When shown a series people like worsted weight yarns knit on 2, 3, & 4 sized needles. When shown a series people think that worsted weight yarns knit on size 1 needles do not show the pattern or consider the pattern too small or dainty for an adult.
People seem to like worsted weight yarns knit at 5+ to 6+ stitches per inch when shown a selection. At this point, I have posed the question to enough people that my poll is starting to have some real statistical power. (And, my wife is starting to have second thoughts about me letting go out of the house or inviting her friends over. She even pities the religious missionaries that come by, as they get invited in, and sat down at the table with a series of knitting swatches in front of them.)
So, in your heart of hearts, what gauge do you like for knit woolens? Not what gauge do you like to knit, or what gauge is easy to knit, but what makes the most wonderful fabric?
