I'm struggling with ideas for what to do for those who have passed. Both of my parents have passed away and my FI's dad passed away when he was young. I don't want to make it obnoxious, but I also want to honor them because they were huge parts of my life until they passed (both from cancer).
I've heard:
pictures with bouquet
flowers on empty chairs (but that would be a LOT of chairs)
memorial candle
Any others?
