Do You Have to Change Anything for Lulu?

Lulu express doesn't do the five by eight size, which is what i use for most of my books. So i just contacted my graphic designer and said, hey, when we do paper back, can you just do a five by eight and a six by nine version across the board? I think that's a great idea. Well, i'm just testing it at the moment. And 's i'm doing all this testing andi tryng to figure it out. But cause i have so many, so many backless books, i just at thought of changen all. The cover quality might be a little bit better on lulu express than i've seen on katy
