I took a free motion machine quilting class, cost me a fortune. The class was given sample squares to start with. They were wool batting, quality cotton fabric, and silk thread for the top and bobbin. Everyone was thrilled their quilting looked so great for the first sample. Then she had everyone sew a sample using machine cotton thread, cotton batting, and muslin. Everyone was shocked how bad their quilting looked. She said if you had done the first sample using the second sampler most of you would have said I can't do this, it looks horrible and be discouraged from trying. Start with the best first!
