Writing structure

by Wickham

I am considering writing a non-fiction "How to" book. In writing the manuscript for publishers, should the lines be double spaced or single spaced?

Mary's Response: Exciting stuff!
I love "how-to" books, so I hope you're successful.

Manuscripts should always be double spaced unless the writer's guidelines for the publisher state otherwise. These days, most guidelines are available online. Be sure to check them out.
