I bought the curvy ruler from Sewkindofwonderful and decided to test the ruler and my ability to cut and sew a double curved block. Before I take a rotary cutter to the two yards of MODA fabric I bought for the intended project, maybe a quick trial run is reasonable. The cutting was very easy. The piecing also was very easy and fairly forgiving. The end product will likely be two separate single block runners. I’ll keep one and I’ll gift the other. But I am waiting for the walking foot for my new Singer Curvy machine before I do any machine quilting.
