This is a simple looking angled scarf/neck warmer. I made this in a James Brett Aran wool with a 4.5 mm hook, but if you wanted it chunkier or larger then just go up a hook size and match your yarn accordingly. I’ve also done one in a DK (double knit) yarn and same size hook and its come out a little looser looking but nice. You can vary this pattern by adding a trim at the bottom if you wanted, or different buttons, maybe even a ribbon where the front post ribbing begins,
Knowledge of front post stitches is necessary, other stitches are just ordinary half double and double.
This pattern is in UK terminology.
