Things you will need:
Cheap plastic cutting mat ($1 at Dollar Tree) http://goo.gl/rh3oYy
Printer (to print out stencil 8.5 x 11)
X-acto knife or hole punch
I added a second version of the mud guard. I extended the guard past the forks to control even more of the muck and mire. Enjoy.
You will need to print out both pages line them up and tape them together and then cut out the whole stencil. (I did this because I figure most people only have letter size paper not 11x17 or the like.)
