I really want to put my return address labels on the envelope flap (opposite side from the guest's address). My reasoning is mostly because I am a little bit anal and I think the envelope looks too crowded with both labels on the same side. I just like the look of it with them on opposite sides better. I know I have seen this done before, but someone told me that I might get them sent back to me if I do this.
I really don't want to get 150 invitations back to me...do you guys know if this is okay for me to do? Or should I just suck it up and do it the normal way with them both on the same side?
