Your stipples look good: nice and even. You have the right attitude, too. After taking my first quilt off the longarm, I thought, geez, I really need to rethink whether I can do this. Of course, I practiced some more and still, two years later, I'm learning stuff all the time--can't tell you how many youtube videos, quilt websites, winning quilts I've looked at trying to learn more and to get some ideas. Just keep going! And have fun, of course!
