Honey, if you've already made a quilt and a baby quilt, and figured it out by yourself, I'm calling you a quilter, not a "wannabe"!!
Do a search here for different things that you want to learn about, you'll find tons of information! You might want to pick up a beginner's book...or google the things that you want to learn...I think there's a YouTube vid for nearly every aspect of quilting!
There are also ladies (and gents?) here that will mentor for you and help you along! (I'd offer, but I'm not nearly confident enough yet to do that!)
Welcome to the board!! :)
