This method had strips to cover the back seams as well. You could hand sew them or you could machine sew them. I chose to machine sew, as I am just doing this as a dog bed, and it turned out quite well. If I were doing an actual quilt I'd have to hand sew it.
I'd be interested in how you do it without having to sew the back.
The class was 7 weeks, each class was about 3 hours long and there was homework.
You take a memory stick with you that the instructor puts all the videos on so you can view them at home while you do the homework.
