Return address on envelopes?

[mj53]

Am I supposed to put a return address on the envelopes I provide for my LOR's to mail in (ya know, just in case)? And if so what address do I use? Mine or theirs?

Or should I just leave it blank and not worry about it.

Are they sending the letters themselves or are you picking them up and mailing them together with other parts of your application (transcripts, etc.)? If the schools allow it, it's better to pick the letters up and mail them yourself (with some sort of tracking/signature required service) -- that way you have one less thing to worry about. If that's not an option, as far as I remember my recommenders all preferred to use official university letterhead and envelopes which had the department's return address. That seemed like a safe bet at the time.
