I hope I'm in the right section, TBH I have no idea what scrapbooking even is.

I was looking at Baby Record Books and hate their layouts and 5yr limitations, so I was thinking, why don't I just make one myself?
I've scanned through the threads and I see that some of you did this also?
How did you start and what did you do? What's this about acid free paper??
I'm thinking you just go and buy a blank book and decorate it.. Is this right, or is there a more creative, prettier way to do it?
Please offer any tips, advice you have, I'm so keen to get started!!
