B.,
First I am so sorry for your loss.
Unfortunately, I have attended several memorial services the last few months so this topic is on my mind. All of the other posts offer great ideas and suggestions! I whole-heartedly agree to do something that she would love and has meaning to celebrate the life she lived.
One of the services we attended was my husbands uncle who passed away very suddenly this spring. Because his faith was meaningful to him, he family had a very traditional religious service. But for the wake before there were a lot of pictures like others suggested. Plus there was a display of baseball memorabelia and some very nice cigars, 2 things he enjoyed and all friends and family would understand.
The other service was a man, I didn't know personally. He was the brother of a dear friend who also passed away suddenly. BUT when I left that memorial service I felt like I 'knew" him if that makes sense. He too was very active in his church but in a non-tradional way, that was discussed. He was a high-school drama teacher and that was discussed. He came from a large family and his only sister (my friend) spoke about how different they were but how alike and gave very specific examples and cracked everyone up! The after service dinner was catered by Hooters because that was his favorite! There were other things too such as the military honors at the end of the service. But everything they did painted a picture of who he was. And as I said before, I didn't know this guy at all, but when we left I knew did.
