My Brother CS7205 sewing machine usually works pretty. The current quilt I’m making is thicker than usual. I am doing top stitching (stitch 65 looks like a maze) and the fabric won’t advance. Someone told me I needed a dynamic walking foot, I had been using a regular walking foot. So I spent $100 to get one and the same thing keeps happening. It’s because the 3 layers of fabric is too thick. My feed dogs will not drop part way, it’s either up or down. My presser foot, same thing. How can I get a little more space so my fabric isn’t pressed together so tight?
