I haven't taken any of the MP licensing classes, either online or in person. However, I have taken a couple of Susan Stewart's heirloom classes on Craftsy, as well as her embroidered quilt class. I think she is a wonderful teacher, and while some of the content was familiar to me, some wasn't...its a rare class on anything that doesn't have something new for everyone. I'd recommend you take a look at them, and if they interest you, wait for a sale and then get them. I was especially fond of her class on Madeira applique and can't wait to do the project I have in mind to use it. I don't remember how much the classes are, but if you wait for a sale I'd be surprised if you had to pay more than $50 to $75, maybe less...Craftsy sometimes has all classes for around $20 each. I don't think you can go wrong! Now if you plan to teach, that is another matter. But if this is just to hone your skills for yourself, then I highly recommend it!
