Some things to think about:
1)After the wedding is over, maybe you can coordinate a weekend or an overnight trip where you can take the drive, visit, get the pictures and share with her some of your ideas for a wedding album. If you want the wedding album to be a total surprise, forfeit the first idea.
2)If you do decide to take the first idea and you consider that today is January 20th, you realize that you still have alot of time to organize page layout, colors, find some stickers, stamps, markers, ribbons, etc. I realize that you will not know everything there is to know about the wedding yet since it hasn't happened, but every wedding clearly has a similar layout.
Some ideas for the wedding album. Try to get some random things from alot of people who were involved with or attended the wedding. For example, you might get some pictures from alot of different people and decide which ones would be good for a nice storybook album. You might want to do a brief page at the beginning of the album that gives a little bit of the couple's background...a picture of their houses as they were growing up, pictures with parents and siblings, senior year pictures, baby/toddler pictures, etc., a lock of hair if it is available. Dedicate another section for dating-pictures at various events, silly pictures, engagement picture, etc. Put some pre wedding pictures in there...the girls getting ready with applying makeup, getting hair done, pictures of bride and groom all dressed up with families, etc. Put a copy of the wedding program in the album. See if you can get some of the flower petals to put in various sections of the album. Maybe put another page with "Couples Favorites" and include favorite song(s), hangout spots, dating activities, etc. Last year, I went to a Creative Memories workshop and the consultant was really knowledgable regarding assisting with layout ideas, content ideas, etc. I have also included the website link for Creative Memories http://www.creativememories.com/ so that you can take a look. On the website, you will be able to find consultants in your area based on your zip code and there are ideas on how to set up albums. I'm not suggesting that you order everything that Creative Memories has on their website, but there are alot of really helpful ideas to get you started as well as helpful ideas for making the album durable and long lasting. Hope you have fun with the wedding and with scrapbooking!! :o)
