This class is about finishing the edges of your garments: necklines, armholes (tanktop, sleeveless top) and hems. A few extra decorative ideas are added to the class, but the main focus is on clean, beautiful finishes. I tried one of the finishings for a knit based on the book (blogpost here ) and that was a success, but till now I never tried others.
Having the book I was a bit reluctant buying this class but I decided to buy it in last weeks sale based on having seen (only partially till now) Lynda Maynards class on fitting. I was far from disappointed. I did watch ALL the lessons withing two days. Which I can not say of all the Crafsy courses I've bought, some are better than others. Lynda Maynard is a great teacher and she shows the steps of construction very clearly and is well prepared. She made sure that it is very clear which side is the right side of the fabric and what is the wrong side.
I'm not a beginner and this might not be a beginners class, but I learned quite a few tips and trics and it's easier to see her doing it then reading it all in the book. Though I'm sure happy to have the book too, which covers more than only these edge finishes.
I HIGHLY recommend this class.
