Have a design using triangles without right angles? Cutting a square in half, just isn’t going to cut it? This is the tool for you. The V Block Trimmer is designed to allow you to cut, sew, and trim square units with two seams that produce a triangle with a point in the middle of one side and two points in opposite corners. The size of strips you need to start cutting your pieces are all conveniently marked on the ruler for easy reference. The V Block Trimmer has seam allowances taken into consideration so that your points are placed precisely where your next seam will meet them. The resulting blocks are slightly over sized so that you then use the same ruler, aligned now to your seams, to trim them to the perfect size. So no more guess work or math, just perfect points every time. This is definitely a tool every serious quilter should consider for their tool box.
