|My local Hancoks offered sewing through an independent teacher. They offered three hour lessons in a variety of techniques and styles, including quilting, how to use your sewing machine, finding your pattern size and style, sewing with fleece, lingerie, booties, etc. The teacher had a good basic program in mind and an array of different offerings each month.
Although a sweet person, the teacher would often show up late, get distracted during the class and walk around the store after telling a student to stitch a seam or something. There was a snowball effect in not having students and the teacher losing motivation. The teacher's sewing was also a bit haphazard in spite of long years of experience and obvious know-how of different methods.
I think if this had been the first or only class I had gone to to learn sewing, I would have been extremely frustrated to the point of giving up. I think I would not have gotten enough attention to certain details (like HOW to sew the seam, rather than justs "sew the seam here," then "okay, now sew there") or theory of how and why. I would suggest prospective students to see samples of a teacher's sewing to make sure it is of a quality they want to learn and emulate.
While I had fun in her classes, I did not enjoy waiting for the teacher to show up on certain days, and lack of attention to each step of the lessons.
