I love my smash book. I don't use it the way most people do. In other words, I don't actually use it as a scrapbook. I have a 12 x 12 book. I like color palettes. I use it for different color palettes that I have found. Then when I get ready to create a card I go to my smash book and look at some of the color combinations to do something different or just get inspired.
I would print these out on my color printer and then cut them down and put them in my smash book. Now when I need inspiration or just get bored with the usual color combinations I can go look through my stash.
