Simply put it is when you create a raised pattern on paper. There are a couple of ways to do this.
1. you can use a stylus and stencil and trace the image
2. you can use an embossing machine & folder.

Plus I think it is the easiest. Simply put your paper in between the the front and back covers of the embossing folder and run it through your machine. Below is a video that explains more about our folders.
