I always liked the idea of the favor having a combined purpose while still being meaningful. The biggest challenge with that is to make it a non edible thing while still being people could potentially want.
My idea was to roll up a photo and use that as an escort card, Before the comment of "no one is going to want a photo of the couple in their household" is given, I would like to say I agree. I would be giving a photo of something that guest would enjoy in their home. For instance some family likes fishing so I could print some lake shots, friends that are more modern can have a geometric design. This would cost about $1-2 per guest with photo paper and ink cartridges.
As a place card I was thinking of a photo frame with the guest's name inside on the back of the chair. Inside could possibly be a letter to that guest thanking them for coming to the event as well as being a part of my FI and I's life. I can get decent frames from the dollar store or in bulk online. Even if the guest doesn't like the picture given, most people would use a frame for something else.
Is this a wasteful trinket or a decent idea? I know the general consensus is an edible gift, but I am not good at cooking and want to have as much hands on as possible.
