I made a scarf for my daughter, using cotton yarn.
The pattern was extremely simple and looks great.
Cast on 30 stitches (or odd number to suit what width you want) knit the first row. Start the pattern:
Row 1- slip first stitch,* yarn over, knit two together * repeat to last stitch, knit
Row 2- slip first stitch, purl
Repeat pattern until it’s the length you want, to finish, knit a plain row and bind off.
nice.
