I honestly think you can send them either all together, or all separately.
And for the SASE, you put another envelope in your first envelope, address it to yourself, and add enough stamps to it to cover shipping back to you. You can use a soft envelope, or a big, regular envelope. It's up to you which one you want to use.

Bump.

Dear FanBiz,

Hello to everyone, I am new and very happy to e a Fanbiz member.

I have a few questions around mailing for autographs, I've been collecting for years but wanted to find some answers to some questions I've had for quite some time, I am largely interested in football autographs and memorabilia, my first question is once I have found the mailing address, in this case for Tottenham Hotspur, do I write the players name on the front of the envelope and then the address? And send the requests separate as there are around 8 players autographs I want, should I send them all seep rare or in one envelope put all 8 letters? I just wasn't sure, I've got no problem sending them all separate I just wanted to know any help much appreciated?

And another question is around the envelope itself I am going to include a S.A.S.E but wanted to know how you go about it, do you include soft envelopes or both request envelope and stamped return envelope hard back?

Please if you have any information it would be very much appreciated

Kind Regards and happy new year!
