I love Stack and Whack. I used to teach the class when I worked at the LQS. It is so much fun to see all the different designs that can come from one piece of fabric. The blocks themselves are not hard to stitch. It's all in the cutting of the fabric. www.bethanyreynolds.com also has some great ideas and wonderful charts on her "cool stuff" page. She give directions to make the pinwheel block in miniture and also gives the setting triangles for many different blocks sizes. Her web site is very interesting.
