I want to start TTM again soon, but it has been like 20 years. I assume everyone still uses envelope, and inside a SASE smaller envelope and an index card asking the person to sign the card and hopefully saying you are a big fan and would appreciate it.

What envelopes and sizes do you use? I also hear many now charge, so I assume you have to use "Safety" envelopes for those people, or since so many now charge do you just use those for all TTM submission?

Thank you.
