Knitted 1 x 1 ribbing is a fabulous stitch for scarves! Not only is it completely reversible, but because the stitches stack themselves in the front and back of the fabric, it's very thick. I find this most comfortable, drape-y, and squishy if I use a needle that is 3 sizes too large for the yarn.
For this exact scarf, I used reclaimed cotton. It was about 6 wraps per inch and knitted on size 13 needles. 24 stitches made me happy. What will make you a happy scarf?
