I made my own as well. I have a binder divided into sections. I like it because I take it everywhere and put examples of things I liked so when I met with vendors or went shopping for things, I refer to my binder so they could have a visual of what I was talking about.
I keep all wedding related receipts in there as well.
In the end it'll serve as my planning scrapbook.
I also have a place I could put quotes I have from vendors for easy comparing.
I did all the budgeting/guest list stuff on the computer.
If I have time in the next few days I'll take a pictures of it.
