We can go up to 52" in one swipe. If we use frisket, it would be two pieces, but we have a low tack vinyl we use for painting stencils with a lotta detail. Just did some 2 weeks ago for a painting company needing the school logos and insignias. Worked great. They were 46" x 32". We made 6 of them.
If ya can't find anyone local, send me a PM and we'll see if we can help you.
