I love the online classes at Missouri Star - they have Quilting Quickly I & the more advanced series, Quilting Quickly II.
I've picked up so many shortcuts and so many good ideas from this series, it was well worth the small expense. The personality of the teacher is fun and positive, the quality of the video is good and the quilts shown are very nice looking - professional and well-made. :)
If I were just starting to quilt, I think I would make this one of my first "tool investments." For about the same cost as a magazine subscription, someone shows you a whole lot of different processes in action - really flattens out that learning curve. :)
