I recently purchased Darlene Zimmerman & Joy Hoffman Tri-Recs for a particular quilt pattern I wanted to try. I know one can accomplish the same block without one, but I'm thinking it is much easier and more accurate, at least for me. When paired together the square is cut on grain. There are lots of fun projects to use the tool with. This is the pattern I am working on now laid out on my dinning room table.
