In Northanger Abbey, Miss Tilney wore a 'very pretty spotted muslin'.  My latest feature in my ongoing series for Jane Austen's Regency World (May/June issue) is on calico-printing. You will be able to find out more about the lives of child workers in the calico-printing industry in my forthcoming book, Young Workers of the Industrial Age, to be published by Pen & Sword this autumn.
