Has anyone ever signed up for any "Craftsy" online classes? I just got an email from Fons & Porter featuring 50% off Jenny Doan's new class called Quilting Quickly Level II: Patterns, Techniques & Tips will have you quilting adorable family heirlooms quickly & easily. It sounds tempting - $29 instead of $59 for the next week. Any thoughts? Supposed to be available "forever".
