How to use: 1.Basically what you do is put your paper over your die or in your embossing folder and sandwich it between the two cutting plates.2.Then you place the 'sandwich' on the platform tabs, (depending on the thickness of your die/folder you may have to flip a tab), and then feed it through the machine with the crank. It will creak and moan when you feed it through and that is normal.3.If you are into paper crafts this is a must have. You don't have to have expensive computer programs to use it and the embossing folders and dies can be fairly inexpensive.4.A novice learning website: https://www.youtube.com/watch?v=hBZcwrTNrYc.
