Quilt shops in the UK are few and far between. When I am in London, one of the places I go for specialist fabrics and trims is Berwick Street. Although the famous Berwick Street Market is mostly street food now, there are a lot of shops with wonderful silks and trimmings for the fashion industry. MacCulloch and Wallis on Poland Street is a proper haberdasher. I am not a fan of Liberty fabric but the shop itself is a delight. All three of these places are within walking distance of each other.
