That’s the challenge to groups and individuals set by a new competition launched last month.
The Court of Lord Lyon and the Flag Institute will also register the winning design.
Brian Payne, Chairman of Berwickshire Civic Society, described the new flag as ‘a long overdue project for the community of Berwickshire’.
It will fly across the county, allowing local people to celebrate their unique heritage and location.
In addition it will provide a definitive emblem for branding local products and services.
The closing date for entries is Monday 31 July 2023.
