I too had that issue (and still do somewhat), and heard about Quilting Makes the Quilt by Lee Cleland and It's Not a Quilt Until It is Quilted by Shirley Thompson.
Leah Day was a fantastic suggestion from someone, and I whole heartedly agree with that!
Also, read comments by some of our members (expecially Charisma), why they quilt as they do. Often the LAer will explain "I wanted to make that pop, so I did this". I have learned alot!
Good luck.
