One of my favorite things to make for baby showers are little chipboard baby books. They're fun, quick, and easy. All you need is a little book (I prefer the chipboard books that spell "Baby"), a cute line of paper, coordinating card stock, and embellishments.
I made the following book for one of my coworkers. I found the paper line and embellishments at Archivers and was able to put it together in the matter of a few hours.
