Honoring a loved one

My fh was very close to his grandmother. I am having cliff links made with her picture so she can be with him somehow.

Wow....this is heart breaking and I'm sure is making it so hard to plan. A nice framed photo placed in one of the front seats and then later next to the guest book is simple. You could also have something of his sewn into your fiancee's suit, so that he is close to him on the day. He could even wear something of his dad's. Maybe find out what his favorite song was and make sure to play that during reception.

I'm lighting a lantern in honor of my aunt who passed from lung cancer.

I've definitely seen the reserved seat or photo of the loved one displayed during the ceremony - consider if there are other family members you may want to honor (grandparents, etc.) and you could create a photo collage at the entrance of the ceremony - which could be a really nice touch if you use family wedding photos to tie everything in.

I agree with other comments about trying to find an item that was special to the father and relate it back to the day (a watch, cuff links, other jewelry, a tie, etc.) or even modify your ceremony script with your officiant to mention his father and how proud he would be of y'all on this special day.

Another item that could be sweet and personal on it is if you are able to find an old document with his fathers signature and have that transferred or printed onto a personalized "gift" for your husband the morning of - a handkerchief, tie clip, etc.
