Create your own stencils using the Stencil Master heatpen.  First draw your stencil design onto a sheet of paper and then place your translucent polyester stencil film over the image.  As you lightly trace over the image the fine cutting tip of the heatpen will melt the stencil film.  

The tool works purely by heat and not pressure which means that there are no ragged edges or tired fingers after trying to control a sharp knife.   Make sure that you put a piece of glass underneath the paper to protect your table.
