Stumbled across this youtube video about a feature available on scrapbooking.com's website. I can see this being very helpful even if you don't shop with them. One of the things I struggle with is picking colors. This can show me options I wouldn't have thought of on my own, and possibly help use up paper in my stash that I tent to avoid.
