Barbican is one of the seven shawl patterns included in Everwear: London Underground Vol. 2.
All the patterns in Everwear, including Barbican, feature a note on the “adjustability factor,” which will explain how you can change the size of the shawl. Keep in mind that changing the size will change the amount of yarn needed.
