Library, library, library. Lots of books, lots of ways to do jelly roll things from easy to challenging. And you can always buy the books you find the most useful. Plus, you might just find something else interesting for your personal "next quilting step." Check the quilts on this board as well as the conversations. I am a jelly roll freak (that is another story) and this is the very best place with the most gifted, nicest people.
Have a good time!
