What size envelopes should I use?

[Dodger4lb]

Hi,
I've never written to a celebrity before, and I was wondering what size envelopes I should use. I am requesting autographs. I might send my own photos; I haven't decided yet.

Should I send and 8x10 SASE just in case their picture is huge?

Thanks for your help!

Most celebs will send 8 x 10's in response to requests that do not include something to be signed. Use a 9 x 12 return envelope with the appropriate postage attached.
