Hi girls

I'll be making a wedding album for a girlfriend of mine using MAX. Her son is getting married in South-Africa and she can not be there. So I thought to make them one each. I think 20 pages. My questions to you are should I put them in a scrapbook or should I make a photo book? The other thing I'm wondering is should all the back grounds be the same or just the 2 next to each other? Does it really matter if each page is different or do I need to keep to a theme? By theme I mean the same flowers and colour throughout? I will be going through the shop for some kits. Is there any kits other than the wedding ones that you think I should use? The wedding is informal and she said white and purple....I hope she meant Lilac lol. Anyways I need some ideas. Please help!!
