First off, thank you all for your wonderful input! So many great choices. I went with Patsy Thompson's Ultimate Free Motion Quilting class. I've made it through the first chapter & I must say, it's quite good.
I was very, very tempted to try Cindy Needham's Design It, Quilt It class. It's 5 hours long (compared to Patsy's 3 hour class) & I know Cindy always gives very detailed helpful tips for how to achieve show-worthy results on your quilts. I think I'm going to be spending my next paycheck on that class because I really just couldn't decide between the two. I loved Cindy's class on AQS iQuilt so if this one is even close to as good, I'm sure it will be chock full of great tips!
There are so many other wonderful choices that you all mentioned. Martina, I agree about Angela Walter's classes. They remind me too much of the MSQC classes & if I wanted that style, I'd watch Jenny Doan for free. And especially thanks to Rob for all the details you included about the classes.
