Both mine and my fiance's fathers passed away from kidney cancer. They passed within a year of each other and all this has happened within a year and a half of our wedding. We want to honor them both for us and for our guests who still miss them dearly. We've thought about making a donation to the Kidney Cancer Association in their honor and having a note at the card table, but looking at other threads about donations made me think this isn't a good idea. Any recommendations on how to honor them?
