I will admit to having a notebook like that when I was a kid. I really enjoyed looking at magazines and clipping out pictures. I bet my parents still have them if you want to see some terrible 90's wedding fashions. I think it was a Lisa Frank notebook and had lots of stickers inside.
But, I know I'll need a wedding planner when I get married some day because I don't think I would know what to do now. And don't worry, you have a lot of time before you have to think about getting married.
