I popped in the local model shop earlier in search and hope of sourcing some 1/43 display cases, no luck with anything i was after. Anyway i also asked if the chap had any idea of how to produce your own decals, he told me the only way to do it is via a good computor program, and like KILOHMANNS has just said with a very good printer.
No idea what computor program though, something like that would be too technical for me, and to be honest i hate things like that, i dont have the patiance for it, i even hate using word :)
