I am considering buying a Silhouette Cameo 2 cutting machine, not for shapes but to design/cut stencils. Does anyone have experience of this and what thickness of stencil material can be cut? Could I use stencil plastic in the machine or must it be cardboard? Is there any other machine that would do the job? It would be so nice to cut, say, a border stencil of just the right size! Any advice would be very much appreciated.
