I just received a ruler today that I ordered recently. It is called an 8" Bias Square ruler. I must have seen a video on it somewhere and decided I wanted it but now I can't find it anywhere and I have no idea how to use the ruler. The instructions are confusing.It seems you use two fat quarters and make bias strips and then use the ruler to make triangles somehow. Does anyone know where I might have seen this demo. It's made by Nancy Martin from the patchwork place. I feel stupid that I bought something I don't know how to use.
