Just how I felt at my first efforts, except I nearly passed out because I was holding my breath while the machine was going! But hey that's much better than I did. I gave up & didn't try again for a while, but as Denise said, drawing freehand squiggles etc really does help. Use a sandwich about 15" square and draw it into 3" sq. "compartments" by pencil. Fill a square at a time before moving on. It is much less daunting to fill a small area and easier to gain control. My cat has lots of practice squares to sit on!
I still have to pysch myself up when starting on a new quilt and I'm okay once I get going - it's the first couple of mins until you relax which are hard. Keep going!
