I use Borderbund's Printshop 20 and got the Click Art Fonts to go with it so I could copy the old font look of the stencils.
I used an Exacto knife to cut them out of card stock that would go through my printer....
Next batch of stencils are going to be cut out of plastic so they last longer.
I also use it to do the 42 round boxes for inside the crate.
