The other day I blogged on some socks with a e-wrap selvedge and 2 x 1 ribbed topper.
The e-wraps I’ve been doing have all been: e-wrap, knit one row, change applicable cylinder needles over to rib needles. So to do that, I actually put the ribber on before completing the first row of knit so that I can switch out the needles at the beginning of the row before the ribber hits it.
I wondered what would happen if I knit 2 rows instead of one before switching to the ribbing.
Here’s my experiment, using Colinette Jitterbug, colour Sahara from stash. (100% merino, a little heavier gauge than Koigu).
A. With One Knit Row before Ribbing

And B. With 2 Rows Knitting before Ribbing

In the top pair, with one row knit, the loops on the selvedge are two stitch (I think) size, while the extra row knitting renders those loops as single stitch size and looks very similar to the edge on a 1×1 rib.
The two rows knit, B, also has the added effect of a piping-type edge. It isn’t/doesn’t roll, just gives a pronounced finish, and on the outside of the garment, not inside against the skin.
(If you haven’t caught it before on my blog, almost all my photos can click to enlarge if you want a closer view.)
Work wise, I found no difference in difficulty or time between the two edges as both require the same number of needles swapped in and out. I suppose the B pair uses an extra yard of yarn for the extra row.
