Hainsworth in the Uk, will have anything you might need. I used their doeskin, which is a lighter weight fabric, to re-line a Westley Richards case. It was a perfect match in both color and weight. If you need something heavier, they have many different series of fabrics to chose from. They even sent me sample booklets of their product lines before I ordered so I could pick the best material.
