I am going to make a sign for the ceremony and reception for my dad that passed away a few years ago. You've probably seen them that say "We know you'd be here today if heaven wasn't so far away." Well, my initial thought was to have a seat reserved for him at the ceremony and have that sign sitting in it. My mom would sit in the next seat, then her boyfriend (that has been around for a while now, so I'm totally comfortable with it and he wouldn't be uncomfortable with this arrangement either, then my brother. Would it be strange to have a seat reserved for someone who had passed away though? And some suggestions for what to do with this after the ceremony is over would be nice too. Thank you!
