Mitch,

You can scan a BG and then import it to your computer... once on the screen you have the long and labourious task of completely redrawing it.
It is indeed long and tedious work which im sure Oldpins will agree on.
Ive just spent all morning vectorising paths for my comp to cut stencils for the rounded black lines on a PF.
4 hrs later and 600 cups of tea and im done.. has been a mind numbing exercise though!

You are correct about redrawing being hard... Its alot easier to start with faded art!
my big problem is I need a scanner that can scan that size! and then I need to get someone to print it on glass.
my local signwriter said he is happy to print onto vinal but thats no good on glass.
I'll work it out one day
