Proposals - Are they double spaced?

[Unregistered]

Can anyone tell me if the general format for submitting Book Proposals is in double spacing? Thanks. Any help on unagented submissions would also be helpful.

You want to single space your book proposal. Print it out on good stock paper, free of errors. One tip. Create a letterhead for your cover letter.

Search the web for writers sites that have articles on writing book proposals. Sometimes these are more challenging than writing the book itself.
