coil bound margins
I’m writing a music book for children. It’s 99 pages long. I want it coil bound on Lulu so it can lay flat. I have set my margins at: inner .80, outer .50, top .50 and bottom .47. Is this reasonable? Also, should the cover be the same?
Later, I want to publish the same book as perfect bound (and eventually as an ebook) for global distribution. I set the margins the same except for the bottom, which I set at .50.
I’m new at this. Am I on the right track?
