Most of the piecing is straight forward, but you do need to get something for the Triangle in a Square patch. The Tri Recs ruler set is the least expensive, and that's really all you need.
I have this book & template set. It was really inexpensive when it first came out!:

Haven't made the whole quilt yet, but did a couple practice patches & liked the template. Looking at the current prices, I'm glad I bought it when I did!
