This knitted up soft and cosy so is quite stretchy. I used colour Northern lights I have knitted this in a plain colour and it does show the pattern more prominent for the front and looks lovely. I used Hayfields Chunky in a deep red.
You can put buttons on instead of using a shawl pin. Use snap fasteners to hold it together and put the buttons on the front as decoration.
This would look great as a full length scarf, just keep knitting to your favoured length, remembering to match the pattern at the other end.
