Well one of the best, I treated myself when I was pregnant. Amy Butler's Little Stitches for Little Ones is well laid out with good instructions. There are projects for every type of sewer from beginner to the more experienced. Gorgeous photography illustrates the twenty baby related projects.
As you can see I have great plans of trying most of the projects. I have made the everything bag with an amazing amount pockets just perfect for a nappy back ( photo to come later) and plan to complete many more with a few works in progress.
