cheers guys
I haven't finished it yet, but there isn't much left to do. I really should just get it done and dusted, so I'll get into it again when I get back from holidays
To start with, the masking was easy to do as I had some vinyl masks that I had bought ages ago and never found a use for until this. They were OK, but became pretty useless after the 2nd colour so I had to make my own ones after that
