Nancy Zieman had a couple of episodes of FMQ on Sewing With Nancy. After I watched them I tried it again and did much better. I did pebbles yesterday and they look like pebbles. I'm still using the start button and low/medium speed. Whenever I get stuck I just stitch in one place till I turn the button off. This just ties the stitches and doesn't change the design.
