Even though you want to jump into stippling, I would say you need to get control of your machine first. I always get my students to start with writing by machine. Draw four horizontal lines about 1 - 1 1/2" apart (just like we did in grade school)on a 12" square of fabric. You can also cover the piece with lines. Make a quilt sandwich with batting and back. Get your machine set up for FMQ and write the alphabet... your name... etc. Remember to fill in the lines completely. Take a breath and repeat. With this excerise you'll get used to curves,loops and other shapes while getting control of your machine. The next step is to draw out the stipple pattern on paper, and/or purchase a stencil for practice. I find that if I can't even draw it, I most likely can't quilt it. And, don't forget to breath.
