AccuQuilt suggests that you line your fabric according to the shape on the fabric cutting die board, not the die board itself. If the blades on the dies are at an angle, you should angle your fabric and just cover the blades. This will ensure the fabric grain is aligned with the shapes’ edges and helps to minimize fabric waste.
