If you have a LSS (local scrapbook store) alot of them have a scrapbook 101 class for newbies. I also would say go easy on the supplies, over half of what I bought in the begining I never used.
The other advice I can give you is this book is YOURS and the really great thing I like about scrapbooking is there is no right or wrong way of doing it. Only YOUR way. I don't scrapbook like my friends, they like to journel I don't. What is important to me is the name, date and where it was taken. That is enough for me and that is OK.
Good Luck and keep us posted on how your doing and WELCOME to the world of Scrapbooking. You will get alot of help and support from everyone on this forum. I've only been here a couple of months myself.
