A Heat Tool is essential for effective embossing. A hair dryer is not hot enough and a hot air paint stripper too fierce (unless it has a lower setting).
Practice your embossing on scrap card or paper until you are happy with the results.
Heat tool should be held approximately 2- 3 inches away from the image.
Heat only until the powder has turned shiny and/or sparkly.
NB: A HEAT TOOL SHOULD NOT BE USED BY CHILDREN
