Chapter start on Recto

This is entirely up to you. What type of book is it? How fancy or traditional do you want it to be? Hardcover or softcover? Trade or art book? Adding blank pages to fit someone's ideal also raises the issue of paper waste. At random, I selected a 1963 softcover edition of The Scarlet Letter from my bookcase. It not only started a chapter on the verso, it was inserted towards the bottom of the page!

Get your hands on a copy of Michael Murphy's excellent book, "Adobe InDesign CS4 Styles." Although a touch dated, the fundamental use of Styles (Paragraph, Character, Object, Table) remains the same. Your investment in learning and using styles is the most important thing you can do to understanding and getting the most out of InDesign.

Scott's suggestion is the correct one. While some mass-market paperbacks save pages by flowing chapters into any position on the page, or onto verso pages, that's contrary to good book design. Make sure your text is one flowing 'story'; set your chapter heads to break to 'Next Odd Page'; and fer gosh sake's learn basic styles and apply them to your work. The small amount of time spent learning this fundamental structural feature will pay off in man-years saved in manually formatting, reformatting, and fixing up documents! 🙂
