I had the same query a while ago, so I bought some international (worldwide) stamps that have a cost of £1.28 and they came with "by air mail" stickers too so hopefully one of these will work for my USA mail that I am yet to send out. Eeek!

But perhaps 2 or 3 1st/2nd class stamps will be sufficient - if it is a regular A5 envelope that isn't too bulky perhaps.......but to be honest, I would love to find out whether UK stamps on my outgoing envelope and SASE coming back to the UK would work too.

So, a lot my most wanted autographs are from people in The States eg. The Pretty Little Liars Cast.

I was just wondering how many stamps I should put on my SASE? I've never wrote to anyone over in America before so It's a bit confusing, if anyone could help me I would be very greatful!

Thank you
