How to do a UK autograph request from the USA

[TimsNuanen0531]

Hello! I am new here and have only done a few autograph requests, always for friends and family, and I have gotten my first request for a celebrity who is outside of America...
I have everything together except I have no idea where to start on the SASE for the return from the UK to the US. I checked out the Royal Mail site and I suppose that is probably where I should get it but...I just reeeeeeeeeally need someone with experience with this to spell it all out for me
If there is anyone from the US on here that has done an autograph request to the UK PLEASE give me all and every bit of advice you have. I would like this done right the first time. I don't have the funds for trial and error lol.
Thank you so much for your time!!!

Hi, I am not from the US, but the UK and send to the US myself so I know about international postage from here. I can try and help. What do you need advice on?

If you need stamps for anywhere you can buy them on eBay, you can find out the amount needed to cover costs to where you are on the royal mail website.
