I'm working on her Underground Railroad quilt from book by the same name. Some of the techniques are great, and I'm having fun learning different ways to do the piecing. I am having trouble with cutting down to size the pieces that are too big. It seems that she includes a very large "fudge factor". Some of my blocks are the right size and others are much too big. I love the Flying Geese ruler but it took a lot of practice to get the hang of it.
