I have found crib-size quilts the easiest quilts to make. They are just big enough to enjoy a design or have fun with putting together a color scheme... maybe even experiment with some new quilting designs... But they are not big enough that they become over-burdensome. Also, newborn babies are SUPER easy going about gifts. Even if you make a mistake, they will NEVER mention it... mostly because they won't be able to talk for a few years.
