Activity for Meghan

This is what we are doing instead of a guestbook. I would like to have a sign asking the guests to sign a leaf, however, I am not very good with words. I was wondering if anybody had any ideas.

Does anybody know about how long it takes to do the processional? I have a pretty small wedding party- only 2 bridesmaids. I'm trying to figure out how much music I'll need.

I am trying to find a song to walk down the isle to. I have listened to several of the traditional options but I'm stuck on one of my all time favorite songs- Metallic's Nothing Else Matters. It isn't really heavy metal and I would want the orchestra...
