TRACE ONTO DRAFTING FILM

Get a hold of some drafting film (Mylar) and trace the pattern onto it.

I'm a bit lucky. Having practiced for years as an architect, I have a cabinet full of old drawings that are perfect!

Now cut out the stencil as before. This time the bridge pieces are larger as they have to be quite robust. They will remain in place and the logo has been designed to allow for this.
