Usually, the sewing machine for making clothes is called flat car, but because the double-sided cashmere coat belongs to middle and high-grade clothes and has no lining, it is not fair in technology to ask for a good look on the surface, and the technology inside the clothes also has certain requirements. Obviously, flat cars simply can't meet such standard requirements. High-quality double-sided velvet coats are usually sewn with special sewing machines, and some places are sewn by hand.

So ordinary sewing cars can't do it. I hope it helps you.
