I have been a scrapbooker now for a few years and everything I learned so far was pretty self taught. I have bought a lot of papers, scissors and other assorted items, but I have always looked for a book that could give me some tips I didn't know or couldn't figure out.
This is the first Idiot's guide that I have read and in my opinion it is the best guide for beginners and some more advanced scrapbookers alike. I thought that one of the best parts of the book were the little blurbs in the margins like "Anecdotes from the archives", "Shortcuts", "Sticky Points", and "Words for Posterity". They made it easy to skim through some sections of the book.
Smedley also includes some anecdotes from her personal experience which enhance the book. But as a more experienced scrapbooker who has discovered many of these techniques through trial and error, I found the chapter on Color and using the color wheel to your advantage to be of great use. Other chapters discuss and explain the language that is used, what supplies to purchase, getting started with journaling and saving souvenirs, creating scrapbooks with kids, capturing special moments in a special scrapbook, and shows a few examples of layouts.
One of the things I have discovered is that whatever layout or size scrapbook you choose to use, is that you find a way to personalize your pages. I sometimes feel like some of the scrapbook pages in the magazines and books are copies of each other and look somewhat mass manufactured. I like to take pride in doing my own lettering and making every page different.
All in all, this was the most helpful guide I have found for the person who wants to get into scrapbooking, but is not sure how to go about it. Most of the other books I have browsed through gave either sample layouts to copy or focused on heirloom preservation, but not what I wanted to learn. If you are just starting out or just want to pick up some quick tips, please consider picking up this book.
