Sarah Veblen is a wonderful teacher! I have taken many of her classes here on Pattern Review. She is very detailed and organized with her lessons. I learned a lot from take both of her knit classes. She provides MANY samples of different kinds of knits and makes sewing with them easy. You do not have to have a overlock or serger. I highly recommend any of her classes. She helps your mind in the process of thinking what you would actually like to do with your fabric in mind.
