A formal salutation. Clean, proofread copy. Use at least 20-lb. Be sure it has adequate postage. Clips Many editors ask for clips so that they can review a sample of your writing style.

Don't send clips of work you've self-published or posted on your own website. And remember, bad clips are worse than no clips at all. It's best to send clips that are relevant to the proposal, if you have them. If you don't, send samples from your most prestigious publications. If you have no clips, don't despair.
