PLEASE HELP WITH INVITES???

OK GIRLS I'm a little stupid when it comes to stuffing invites.

So I'm hoping maybe you can help.

So, There is the big envelope and the medium envelope. Everything goes in the medium envelope (invite, then the tissue paper on top of the invite then what?? Then the response card and the card that says where the reception is??? Where do I put the direction cards and the hotel insert??

Also the response card and the reception card is like a little card in itself. If that makes sense. It is shaped as a rectangle but only half is outlined. There is a crease but I'm not sure if I fold it over and then lay it on top of the response envelope???

Please help???

Thanks

Jamie
