SCENTED ITEMS
Why not add a few drops of fragrance oil to your finished casts? (You can't add it whilst mixing 'coz the oil and water won't mix!). I make pastel casts from some of the smaller moulds that we sell, (such as the Dolphins and Shells and Starfish), and scent these afterwards. People use them as room fresheners, placed in a container maybe together with their pot-pourri! They're great sellers!
