Format is wrong
I just received my book (I ordered just a few to make sure everything looked right), and I could use some help.
I used the 6x9 template and uploaded it per the instructions. In the final product, the margins are very large and the print is very small, not the way it looks in the file I uploaded.
I'd like to order 250 books asap, but it can't look like this. I'd be happy to provide the file and a sample of how it turned out if it would help.
