In seminar days this was referred to as a”fern leaf” pattern. Holding groups in these sequences gives a bit more swing to the side of the finished piece. The difference between these fabrics and the ones that look like this swatch
is that when the row of held sequences is completed from one side to the other, at least 2 rows are knit across all stitches before reversing the holding direction and moving toward the starting side to complete the repeat.
In addition, there is often a tension change between the groups that pulls the fabric inward and enhances the texture. In my sample the held segments were knit at tension 6, the tight rows at tension 3. The pattern is a multiple of 8 stitches +2. To knit: cast on the required number of stitches, the first four rows are tight, so waste yarn and ravel cord followed by cast on and tight rows is recommended. At T3 knit 4 rows, COR. Set the machine to hold stitches. T6: bring all but the first 8 needles closest to carriage into hold. Knit 12 rows. COR: on the side opposite to the carriage but closest to the needles in working position, bring a group of 4 more needles into work. Knit one row. COL: on side opposite the carriage bring 4 needles into hold. You will now again be working on a group of 8 needles. *Knit 11 rows. COR: on side opposite carriage bring 4 needles into work, knit one row. COL: on side opposite carriage bring 4 needles back into hold.* Repeat *to* until the last set of 8 stitches are in work on the left hand side, knit 12 rows, ending COL. T3 knit 4 rows. Reverse process, moving in opposite direction, beginning with knitting 12 rows on the first group of 8 stitches on the left.
the fabric swatch
If the goal is to retain the texture, a yarn with “memory” ie wool is recommended; if a yarn such as acrylic, which has the capacity of being “killed” when pressed (sometimes the desired effect) is used, the result may be seen below

I had previously shared other images of this type of fabric, they may be found in my previous post, described as “horizontal cables”http://alessandrina.com/?p=2838. The sequences there illustrate use of other results from varying the number of stitches and rows in each held group, as well as the biasing that results when all rows of groups move in a single direction.
