When mailing in additional info by mail, what kind of envelope do I use?

<p>Do I use a big manila one or just a regular envelope? I have to send additional information to Fordham and Georgetown (cannot/not using the Common App for these two schools so I can’t just attach it online).</p>

<p>o.o I just used regular ones, I didn’t know/think we were supposed to use special ones.</p>

<p>Just a normal envelope is fine.</p>
