Jennifer Stern is the instructor of this video class. It was excellent. I learned so much--not just about her tee design. She gave so many useful sewing hints that I can apply to my knit/woven fabrics. I'm serger-shy but she made it look so easy to sew the tee on the serger (or sewing machine) I was eager to try it. It was a success. I learned about using the serger to sew because of Jennifer. I love the fact that the class was video instead of written lessons with or without videos. This was an all-video class. I'm a visual learner so her videos were perfect for me. She also answers questions promptly. I would definitely recommend this class.
