Are there any classes you can take? Skill building classes can help tremendously. Check with your LQS to see if they offer anything like that.
If you don't belong to a quilt group, sometimes they can also be very helpful. Is there a quilting friend near you that you can have come over and sew together? I'm sure each of you would learn something from each other. :)
Don't be discouraged, you said yourself that you're seeing improvement so you're going in the right direction. :thumbup:
