Well, I finally got my story done (certainly took long enough...), outside of hopefully coming up with a new title in the next couple of days, so I'm just about ready to mail it off to its first magazine. I've already got it formatted, and I made sure it followed the submission guidelines and all that, but I was wondering about the SASE. When sending in short stories, is the SASE supposed to be a manilla envelope, or a regular letter-type envelope?
