I can answer 2 of your questions- WM is Walmart. I have a 301 but haven't fmq'd on it yet. Am looking forward to it, though. So far, I've done about 9 but on a different machine. The last one I did I used stencils- entwined hearts- I marked my quilt with a thin bar of soap. It worked great- was fast, stayed on it and washed right out. I also used one of those blue quilt marking pens that came out simply by spraying a water mist on it. I've also read that you can use washable crayola markers. I'm going to try that next as you can buy a whole pkg. of those for the price of one quilt marking pen. But, I'll try it on a scrap first, of course.
