My tree is pretty wide. I can print it 6 sheets wide by 4 sheets high using legal paper and it looks pretty good. But then I have to tape all the sheets together. I tried exporting to PDF and asked Staples to make an "Engineering Print" 36"x48" but they say it gets blurry at that size. Is there a way I can tell Family Echo website to export as PDF for 36'x48" paper?
