I see lots of TK brides getting their parents thank you gifts. I hadn't heard of doing anything more than a photo album as a thank you gift until TK. I'm leaning towards just giving them each a photo album and a nice thank you card/letter, which they'll get when the pics are in and we can get the albums made. It just feels weird to think about getting them more than that.
So... what all are you doing, and why?
