Stencils

How do you intend to make the stencil?

Manually cut it out of carton/plastic/… or do you have access to a cutter/laser/…? 

In the latter case I would assume those will need vector input and Photoshop might not be the best application for the task. 

Would the stencil be like a sheet of paper with cut-outs, or on a woven screen, like a silk screen print?
