Congrats on beginning to scrap. It does seem overwhleming at first, but I find looking at other people's work is a great way to get inspiration. (I prefer
www.twopeasinabucket.com but there are lots of others.)
My top 5 list for a beginner (assuming you have an album and photos!):
1. 12" paper trimmer
2. Great scissors (I like cutterbee)
3. High quality adhesive/Glue squares
4. A few stacks of plain and patterned 12x12 paper (or whatever size your book is)
5. CK Becky Higgin's Book of Sketches (1&2)
I start almost every LO by finding a sketch from one of Becky Higgin's books or a CK magazine, and most of the time my pages morph into something else entirely, but it always gives me a starting point, so I don't feel so overwhelmed. I would also highly recommend a subscription to Creating Keepsakes. "Scraplifting" is not a crime!
As someone already mentioned, watch Michael's, JoAnn's and Hobby Lobby for the 40% coupons and sales. I never pay full price for albums or idea books.
And my last "rule"... there are no rules! Make up your own techniques, build on those created by others, etc. And most of all, have fun!!!
