Saw this in Fawkes projects and wanted to try it. Used leftover sockyarn and like how it looks in ribbing - not too loose for my taste, even with 4 mm needles.

With 60 stitches, it is about 15 cm wide unstreched, and 61 cm long - so app. 1 50g ball would be enough. If I did it again, I would probably go for 72 stitches to make it a little wider. Length is ok, maybe a tiny bit longer.

I even understood how to fold it (I think…) when looking at all the other project photos.
