Learning is definitely something to learn, depending on how high you ask yourself. If you are not strict with yourself, you can go to the general curtain training class and go through a process. If you are very strict with yourself, I suggest you go to Ke Qiao Jingtianwei Curtain Training Course, where there is a complete training curtain, from measurement, budget, design, tailoring, sewing, installation, matching and sales. The teacher's teaching is strict.
