Pull out all the cut masks for the first layer,boy was it fun hacking that lot out I can tell you.
In response to some email enquiries, most of the mask templates i'm using can be got at
this page on Starship Modeler
It will open a new window.
All in downloadable pdf files and with instructions, so all you need is some time,
several sheets of frisket film and a printer.
Apologies for not adding this info sooner, I knew there was something I was missing in the waffle.
Ah well...onward!
