Heat embossing is a crafting technique that creates a raised design on paper or other materials. It involves applying a special powder, called embossing powder, to an area where a design has been stamped with a sticky ink. When heat is applied using a heat gun, the powder melts and forms a shiny, raised surface. This method is popular in card making, scrapbooking, and other paper crafts. It adds texture and visual interest to projects, making them more appealing. Heat embossing can be done with various colors and types of embossing powders, allowing for creative customization.
