|First online class ever....returning to sewing...advanced beginner. INSTRUCTIONS were good. Glad to see the course extended indefinetly for reference. Wondering why videos were offered additionally!!!!Maybe I missed something on narrow chest alteration as I ended up referring to other reference books on hand. Wondered why chat classes were cancelled after registration....not having partaken in this format I dont know if that was a plus or minus. HOWEVER, making a muslin really solves a lot of problems a good procedure to stick with.
