I do not think I have a pic of that scarf at hand. But I will take one. (One scarf I gave away, but that original one I still have).
Basically how you do it:
row 1: RS: k1 (border) then: *yo, k2, lift yo over the 2 stitches dropping it* repeat until last stitch, k1 (border)
Row 2: WS: purl all stitches
That is all there is to it, just repeat as many times as you want.
You can also work the row 1 every 4 rows.
Or you can work the *yo k2 slip yo over* then k2 and then repeat and do that offset every 2 rows.
Warning of my part: bamboo stitch rolls, maybe even a bit more than st st. But for my fashion scarf that was perfectly allright for me. (it basically looks like a tube but is not sewn down)
Very fast knit, pretty much nothing to memorize and great effect.
