I love Anita's Arrowhead. It is easy to make yet looks complicated. It is also very versatile in that you can change the size of the block rather easily by just adjusting it proportionally. I've made everything from coasters to 12" sizes with it. If you goodgle Anita's Arrowhead it is a free download. While you're at it check out other of Anita Grossman Solomon's wonderful blocks and books. She is a genius of making the complicated looking block simple to construct.
