I went to Barnes and nobles to look at all the books and binders. I was able to open them and see the weight and size differences. I wound up going with this one: https://www.amazon.com/Simple-Stunning-Wedding-Organizer-Celebration/dp/1584799021
It is perfect for our smaller beach wedding! Lots of room to craft ideas and take notes and it's a binder so it was easy to add my own pages!
