twisted stitches are not wrong.. but they are not part of standard stocking knit.
(just as cables aren't part of standard stocking knit, or purls (on front of work)
twisted stitches are twisted stitches.
stocking knit is defined as:
ONE side of work, knits, the other side of the work, Purls.
it's not alternate rows of twisted knits and plain knits.
REMEMBER--knitting stitches are defined by how they look, not by how they are worked.
so Purl every row is just a valid a way to make 'garter stitch" as is knit ever row.
and K1, P1 is the pattern for 1 X 1 ribbing (even number of stitches--every row)
and K1, P1 is the pattern for seed stitch (odd number of stitches--every row)
same basic directions, very different fabrics
The FABRIC (outcome) is what is important, not the process.
if you have alternate rows of twisted stitches in a fabric that is supposed to be stocking knit, you don't have right!
if you have row after row of knits on one side, and row after row of purls on the other, it is right, no matter what process you used to get that effect!
